Easy to assemble, sturdy and robust. Heavy, getting out of the box. But... It's only cardboard. Well packed, but you will need some elbow grease. I'm half blind and put it together in under 2 hours including getting it out of the box and moving to my garage. Great product for now, haven't really stretched it's legs yet.

The R6 retro is our second Isinwheel bike. We love both. We have this R6 Bike and the U7 cargo bike. Both are awesome. One of my daughters rides around the college campus and the other around our neighborhood. They are so much fun.The R6 came with a battery issue and Isinwheel customer support was very responsive, identified the problem and fixed it.We plan on buying one more.

I like this as a beginner e-bike. It works pretty well but for the price point, don't expect remarkably good parts, it's just good enough. So let's dissect it a little bit. This bike was not built to be light - 87 lbs. and you can see it in the parts. Not even sure the frame is aluminum, as claimed. On flats, I tried to reach 28MPH but fell quite short, not even breaking 25MPH. But it might just be me. 55-75 miles range? Good luck. And good luck just might get you to 25. I live in a hilly area and so far, I'm getting 15. After five decent hill climbs, this ride gave up the ghost and forced me to pedal the last 2 miles home. The following day, the battery recovered to register 3 bars out of 4. Shocks are pretty good front and rear, if you can ignore the clunking sound in the back for the first couple of minutes. It stops after a few actuations. And it just might be this bike. The 7-speed Shimano drive train is great, But the cable-actuated brakes are so-so, with the rear requiring a lot of grip pressure to stop. The front is OK. It will stop but not immediately. For the weight of the bike, it deserves bigger rotors and maybe a front 4-piston hydro. Battery is by Jetech - 13Ah but no UL cert on the battery. Purportedly, the bike has a UL2849 cert, so maybe its covered. Seat is man-made leather but it's just as well. The electric motor is not brand name but seems to be fine. It is rated at 1500W, but I'd say that is a peak-to-peak value and is really just the usual 750W Peak Power value that is a typical size motor for e-bikes. LCD screen washes out in direct sunlight. Lamps are OK but might not be rated high enough for legal nighttime use. Horn is "meh". This bike is best for flat roads. Great for beginners. 20MPH is plenty fast for most adults. After less than 30 days and 20 miles, I'm moving on.

Tires go flat had four in two months. lucky to go twenty miles on a full charge
