R5 - Excellent Bike!
I bought the R5 Pro with 2 Batteries to replace my ReAspire 26x4 folding ebike with the same frame style I’ve had for 4 years and the Amazon seller has disappeared. I put 5,500 miles on my former ReAspire before the lower fork cracked on the rear. When I found the R5 Pro it was the nearest replacement to my beloved ebike I’m so used to. First Problem: I ordered the R5 Pro thinking it would be an upgrade from the ReAspire 750 Watt motor as the R5 Pro is advertised with a 1,000 watt motor peaks at 1,500 watt. However, the R5 Pro I received came with a 750 Watt Motor as indicated on the back wheel’s motor (see photo). I double checked the listing and sure enough the R5 Pro is sold as a 1,000 watt / 1,500 Watt peak. After contacting the support they explained to me that models manufactured after late 2025 have a 750watt motor with peak of 1500 watt. This is a good thing with new laws coming out about motor sizes. The motor does power the bike extremely well. Second Problem - Turning radius: This bike has extended front forks that extend above the frame and the extended, upper fork is where the headlight mounts. The issue is this limits the turning radius and requires wide turns whereas my previous ReAspire has a lower fork that allows full turning radius. To me this is a safety concern but there’s not much that can be done with the extended forks. I’ll get use to this turning radius over time. Otherwise the bike went together well. The instructions manual is awful for assembly. I had to go find YouTube videos to figure out small things like front wheel mounting and headlight mounting. Headlight: I was looking forward to finally getting a bullet style headlight and this headlight does the job! Seat: The seat is good quality but I prefer the Cloud 9 seat and have upgraded mine. Speed: I was able to reach 26mph pedaling on PAS 5 the highest setting. Tires were inflated to 20psi and brakes were properly set and no rubbing. I’m 185lbs and this is fast enough. Battery: I am noticing 20-25 mile range in a combination of PAS 3 - PAS 5 average speed mph with the headlight on. I believe the only way to get 50-60 miles is PAS 1, full pedal without the headlight on. The 130 range for 2 batteries is excessive, but possible. Having a second battery is nice, but not something I would carry with me on the bike due to the 15lbs weight. As well, folding and unfolding the bike is not an easy task to swap the battery. It would have been nice to mount the second battery in the rear rack with a switch to switch between them for longer distance but that’s not an option. You have to fold, replace and fold it back. Thankfully my last bike, the ReAspire’s battery lasted 4 years with daily riding and recharging and still going. Hopefully I will never run out of batteries having two of them before other major components fail. Brakes: Exactly the same Logan hydraulic brakes as my ReAspire. I couldn’t find a Logan brand replacement for these so on my other bike and I changed calipers and handles at 5,000 miles. I assume these will last as long provided changing the brake pads every few months (heavy ebike eats brake pads fast). This is definitely a larger bike than my ReAspire and feels like a “pro” version of that. Overall I am impressed with this bike. I recommend for any serious adult riders. I upgrade my tires to Origin 8 street tires and Tannus liners and have only had one flat after 4,000 miles of trail riding and have upgraded my R5 as well. Smooth riding. Happy customer.

Great bike for us big gals!
UPDATE: I've had it for a bit now, and I can say that yeah, just like the other reviews, the battery life isn't as great as it claims to be, and when the battery is down to half, it's much harder to pedal. THAT BEING SAID: I'm still super happy with my purchase. It gets me home in 15 minutes, versus the couple of hours it usually takes me to walk, with the fibro. The only other thing that bothers me is the fenders are *super* rattly/loud, but that's really just a noise/cosmetic issue. Nbd! Don't mind the terrible video with me complaining about the seat, where you can't see anything but the road. I just wanted to show what it's like on the throttle! Okay, so, to start with - I am a fat girl. Not your average, "aw, chubby girls that weigh 5 pounds over the average are so cute!" fat, but the kind of fat that makes my kick more akin to a mule's after walking 4 miles back and forth to work for nearly 14 years. I was terrified I'd sit on this thing and crush it like an empty soda can, but to my surprise, there was no screaming death squeak as I sat in the saddle. The full suspension is truly a godsend, because I'm not sure what I'd do if I sat down and the wheels popped off and broke my neighbor's windows and/or his bones. Secondly: This thing hefts my 380 pound ass like I weigh NOTHING. I'm not kidding. I was afraid it would be a chore to get it moving, but the pedal assist works like a charm, and I hardly have to put forth any effort unless I want to, which is awesome! I have fibromyalgia, so I was nervous I'd get stranded somewhere if I wasn't able to pedal back, which brings me to my third point: the throttle on this bike is wonderful. You can go purely on electric, just by pulling the throttle on the handlebar back, and it zooms me along from a dead stop as fast as it would with a skinny person in the seat. I'm not afraid to go out for an exercise ride, or go to and from work, because I know I'll be able to make it back. The bike came with a rear rack, which was super nice and sturdy, some mirrors (which I couldn't fit on the bike...the clamps just didn't fit, or perhaps I am stupid and/or losing my mind after working for a place that rhymes with hallfart for so many years. Anyway! It also came with a bike lock and key, and a neat phone holder, which I used to hold my phone and listen to Saint Mesa loud enough to make my neighbors wonder who the watermelon shaped weirdo with the stuffed animal cat backpack zooming down the road was. The only downside I'm seeing is, one, the seat, even though I imagine quite comfortable for skinnier people, as it's VERY cushy, makes me feel like I've been hit in the coochie by a crowbar a few times for saying a bad word in front of somebody's southern grandma - but like I said, that's likely just because I'm fat. Nothing a gel seat cover won't fix, for some extra padding! The second downside is, the wheel popped out of it's casing a few times before I was able to really get it to stay in there, which is worrisome, but fine I guess if it doesn't happen again. In that case, perhaps I will lay on the floor for two weeks and cry. I'm really happy with this purchase, but I've also only had it for a couple of days. I'll come update this review in a month or two after I've gone back and forth to work with it for awhile!

BEST BIKE PURCHASE!!!
The Burchda R5 Pro e-bike has completely exceeded my expectations in every way. Its powerful motor and smooth acceleration make uphill rides and long commutes effortless and enjoyable. I was especially impressed with the battery life—easily lasting me over 45 miles on a single charge with pedal assist. The build quality feels solid and premium, with a sleek design that turns heads wherever I go. The fat tires handle rough terrain, gravel, and city streets with impressive stability and comfort. I also love the LCD display, which provides all the essential info at a glance. Overall, the R5 Pro is an outstanding e-bike that delivers performance, reliability, and style—I highly recommend it!

Over all I'm happy with this bike.
I've had this bike now for a few months and I've been holding off on writing a review. The first thing I like about this bike is it looks like a traditional mountain bike. Most E-bikes look like they should have circus bears riding them. They are just so weird looking. The next thing I like is how much fun it is to ride. I personally don't ride for exercise, I ride because it's always been fun and now that I'm older, the bike makes it so much easier to just enjoy the ride instead of having to get off and walk it when I just can't hack it. That being said, even thr steepest of hills are challenging at the highest setting. The battery is super great too. I've gone for a few 10+ mile rides and barely made a dent in it when fully charged. The best thing, for me though, is it can fold in half. I live in a one bedroom duplex and the fact it can fold saves me a bunch of space. That said, there are some downsides. One is the fact you can't reset the odometer unless you havw the company's crappy, and rather sketchy, mobile app. The other thing I've noticed is that the gears slip when I'm going up a steep hill. This might be my own doing because I keep the gears at the lowest setting but I am not entirely sure. I personally don't ever having these types of issues on a regular bicycle. The other thing that sort of stinks is the weight. If you have to go up stairs, like I do, to get it in and out of the house then the weight of the bike is killer. Overall it is a really good purchase. Despite the negatives the price is just too good if you're looking for aan e-bike that can fit into a small storage space and still get you too and from your destinations with no problem. And when compared to other E-bikes, the price is just worth it in the end.

Nice Ride
Stronger and better with more features than I expected. Also just a bit heavier, but that’s ok. I averaged 10 miles in each of the first four days of use, and now have it ergonomically adjusted to my liking. I added saddlebags and a longer mirror. Came with a decent bike lock and storage bracket too. Instructions were not model-specific. I’m a big guy and this is a suitable big bike.

Bad Battery Range & Strong gearbox and Pedal Noise - No Customer Service support.
I am faced four critical issues and I did contact Customer Service (Suzan) before I leave a critical rating, unfortunately no success. 1- The bike I received was not new, mainly because the display worked without me needing to use the password. I didn't do anything and it was already working... and also because there were signs of assembly tools on the item to be assembled, such as the front wheel 2- Battery Range is ridiculous, to fair away of the seller specification. I just used pedal assistance , I used the bike 3 charges to really take care average of Battery range and I was never able to reach 19miles of range using pedal assistance (P2/P3) .. this number should be 50-68miles .. all in all, something is wrong with this battery as it is capable just 30% of range specification. *remarks: my weight is 198lbs. 3- The bike makes a lot of noise on the pedal, when I'm standing still, just when I put my foot on it to start the movement, it makes that squeaking noise... and when I actually start pedaling, the noise is very loud and unbearable... it stops. that there is a lack of lubrication in everything or there is something wrong. 4- The gears are not adjusted, when I do an up or down shift, the gears don't engage correctly, it keeps making that noise that it hasn't engaged and when I pedal hard, it jumps gears (pure Gear jump out) and makes a loud noise. This happens mainly in gears 3-7... The gears have not been adjusted. Good points Bike has good and strong aluminum frame.

Amazing. One downside, but not really their fault
I've just gotten this, I've only put 12+ miles on it and that doesn't seem to register on the battery yet. I've been using lots of motor, levels 3-5, for all that riding. I'm happy with the power & speed. I don't love the motor control: this is my first ebike so maybe I'm being picky. The power levels, 0-5, really equate to the top speed (top pure-motor is around 23 mph). Whether that's triggered by pedaling, or twisting the throttle, it turns on pretty abruptly and plows forward. So there is no nuanced speed control: if I want to slow down for a sharp corner, I either brake (thereby turning off the motor), and/or I switch to a lower power level, which is inconveniently done with the left thumb. That all makes it finicky in city traffic, to me. I wish the throttle worked like a motorcycle, variable speed. That said, it's all new to me, and I expect to get better at it. There might even be settings or something I can change. Note that if I go into that corner having braked, but not having turned down the speed, and then pedal little, it will snap back on which can feel quite dangerous in a corner. Again, this may be user error, maybe there's a better way to do corners/slowdowns. The big downside that I hadn't accounted for is how wide the frame hinge/lock mechanism is. The first time I rode it I smashed my knees into it whenever I pedaled, which was excruciating. I put some padding (cardboard) over the joint, and the problem went away: no sharp metal edges, and my knees sort of gently slid against it. I'm going to figure out a better strategy, probably just prettier padding. I expect to be peddling most of the time, so that needs to work for me. I briefly thought about returning it if I couldn't work around that, but 1) that's the cost of foldability, and 2) I think it's really important to be foldable, for me. Many people could probably live with 20" wheels, which would move that joint much lower depending on the design. I really like the 26" wheels, though frankly the bike feels gargantuan. Which is fine. The major reason I got this is to commute and run errands. I wish it came with integral wheel locks and a key on/off switch, but none of them do as far as I can tell. I think I'll get 1-2 disk brake locks for the wheels. I may try to rig some way to disable the power to it. I like that the battery is locked in. It is heavy, but I can carry it briefly: it is very unwieldy, especially when folded. There's a welded-on bracket underneath the that protects that sprocket, which reduces the clearance by around 2" I think. It's just the size to get in the way pushing it up or down stairs, which is really tedious. I might cut it off. That said, if you misjudged and bottomed the bike out on it's sprocket, something would break, and it could be your bottom bracket there's so much weight involved, so I appreciate the sentiment. It went together very easily. The headlight was a pain, but that's mostly b/c I mixed up the bolts. It's a somewhat finicky bracket design, and way larger than it needs to be, but bright enough I think and solidly mounted. The rear light seems nice and bright too. The seat light is powered by a little battery, and it's very easy to trigger when you grab the seat, so I expect to run that battery out in no time. I may add more lights, but this is a very good start. When bolting on the rack (it comes 1/2 installed, you just have to swing it down and install two bolts), take some large pliers or a crescent wrench and gently twist the tabs a bit before you install the bolts. It's quite easy to get good alignment with the frame, but those tabs arrive straight instead of angled (with the frame), and you wouldn't want to install it without better alignment between the frame and those tabs. If it weren't so easy to fix, I would subtract 1/4 star for that. It took 30 seconds. Just do it. The rack is amazing. I mean, I haven't actually used it, but it seems insanely solid. I had expected to swap out the seat b/c I'm very picky, but I'm enjoying it's comfy plushness, so maybe not. So far, I love it. My only durable complaint is the lack of nuanced real-time speed control. As I learn more about that, maybe I'll get used to it, or maybe I'll try to figure out how to install a different controller, which would be a huge task. I will try to rig some disable switch: without removing the battery, I don't think there's anything stopping someone from coming up, turning it on, and spinning up the rear wheel, which would not go well if there were disc brake locks installed. So yeah. It's a great bike for the price. Good workmanship. The horn is probably good for traffic, but too loud for pedestrians: I'll get a little ding-bell so I don't scare people out of their pants. Oh, the brakes in combo with the big tires are powerful. It feels like I can stop as fast as I dare. It's a g-force thing. I expect to add panniers for grocery shopping (looking at these: https://www.amazon.com/gp/product/B0C7FS24PJ/ref=ewc_pr_img_2?smid=A2YNSTVTK080NE&psc=1) and I already ordered puncture-resistant tire liners: the tires are very soft and flexible, and I worry that they wouldn't last through all the crap I ride through and over in the city. I'll probably put on heavier tires when I replace them, but I'll probably ride these until they're spent. They are very sticky/conformable, so fantastic incredible traction. The shocks, which I don't yet know how to adjust, are cushy. It takes speed bumps better than my car. The combo of the big tires and shocks makes this a really great city bike: no matter what road situation I might get forced into (potholes, curbs...), I stand a better chance of surviving surprises on this than any bike I've ever ridden. That frees up road-surface-attention for situational awareness. This is part of why I got 26" wheels, less susceptibility to small-object encounters, and I immediately noticed that I spend less energy trying to see every detail of the road ahead. If I smack into an unseen speed bump, the jolt won't be fun but I will probably keep on trucking just fine. I'll probably add more later. So far so good.

Great bike, Good power, Very FUN!
I wanted to give some time to truly test the R5 Pro before giving it a quality review. This is long but hopefully will alleviate any hesitation on purchasing. Over the past 6 months my friends and I have ordered a total of 7 of the R5 pros and I have personally put over 700 miles on mine split between road, dirt trail, and truly offroad terrain. Our e-bike gang consists of a wide range of riders 21-55 years old, 100lb to 250lb, 5’4-6’2 in height and of various athletic abilities. I have written this with all perspectives in consideration. Pros: - Long range/Battery life – As many reviews before me have noted the range is great. This is dependent on a number of factors. Terrain, Power assist settings, shifting gears, maintaining and cleaning the bike chain and cassette, and rider weight. Our average ride is around 30 miles but we have taken them on rides of up to 70 miles without an issue. On longer rides we do keep it in PAS1 and have returned with 2 or 5 bars on the battery. I am confident we could get 80-90 miles if we tried. That said it is tempting to dial the PAS up which takes away from the battery life. Do not buy this bike thinking you will go 30mph for 90 miles on all battery. Also note that battery anxiety is a real thing so until you are comfortable with the range do not plan long rides. Take it slow and get used to it first. - Off-Road Performance/Power – Breaking this into two parts off-road and road. I have ridden the R5 pro on some pretty rough terrain with some steep hills, ruts and logs in the path etc. In this kind of terrain the R5 pro handles it like a champ. It is not like riding my hardtail Trek bikes at all. I can reasonably maintain 8-10mph safely. The challenges are the bike is heavy (72lbs) and top heavy with the high battery placement. So there are times that it can drag you over if you are not careful. I am 6’2 220 and I have managed to buck off once but my wife is not comfortable riding the trails due to this. Also note your battery life will suffer on offroad due to the increased load. - Road Performance/Power – This is excellent. We easily go long distances and can go up to 32 MPH when diving in hard. When riding on PAS1 we average about 12mph on road and PAS5 easily reaches 25 without peddling. Note again PAS5 will kill the battery. On PAS5 I would assume a range of only 15-20 miles vs riding in PAS1 has been proven to us to go 70 miles easily. Usually we do a combination. - Quality/Value/Assembly – Across the 7 bikes I have built the longest part is opening the box and cutting the 100s of zip ties to protect these things. I am able to assemble them in around 15-20 mins once everything is opened and laid out. That said the instructions are terrible, you kind of need a gut feel on some of the less obvious parts. Also there has been some lite variation between the bikes. Having ordered and assembled so many I noticed the breaks, front fork, fenders, latches and other have changed. Nothing out of the ordinary as they improve the bikes but this has led to some variation in the builds. IMPORTANT tighten all the bolts not just the ones you expect to. Most clicks and noises on bikes are related to loose bolts. On 2 of the bikes we had an annoying click that took awhile to diagnose. Turned out it was the pedal arm was not tight enough. Not a quality issue. - Customer Service – Across all the bikes we have only had one issue and it was minor and customer support was great - Size/comfort/features – These are big bikes and demand a presence. That said my wife has no issue controlling the bike on smoother terrain. The twist throttle is a godsend often and utilizing it will vastly improve your experience. The headlight is bright and we have no issues riding after dark, although it is not preferable it happens. The horn is loud enough that you can make people with headphones on jump so does the job haha. Comfort wise I have a lot of experience on bikes and these are not bad. I mean obviously you need to build up some butt tolerance but that’s normal. The Seat is better than most although it does have a button for the light that has poor placement. The only performance upgrade not included in the bike as you may notice in many reviews is the pedals. While they are not bad they can be slick with wet feet. I changed mine out to some gnarly ones and love them. We also put bags on the rear rack to hold bike chains and I always carry the tool kit that came with the bike. - Documentation/resources – There is a Burchda Facebook group which has a reasonably good community. The YouTube Videos can be a bit misleading in my opinion due to changes in the bike. The App does not work with most bikes but is really not needed the settings are all adjustable on the d-pad but I caution you on this as the flexibility in there could break things if you are not careful. All this said the reason we have so many is almost every time someone new rides one they get excited and start looking into e-bikes. Everyone loves these things and we clearly found a winner. Several more of my friends intend to buy at least 3 more over the next few months leading to 10+ in our crew. So after all this I highly recommend these even compared directly to some very clear competition that may look better but are not.
