BEST INVESTMENT WITH BLACK FRIDAY SALE
Best and most affordable set of wheels for a handicap. Definitely worth the price. Battery last up to 15.5 mile an without pedal assist. Disk brakes to help with the immediate stopping. Assembly took about an hour thanks the stars they had video assembly tutorial and build… it’s a little slow up hills but I ain’t complaining cuz I know my weight is the reason for that.

Great Bike
I recommend this bike for a starter bike. I did have a little trouble with a squeaking noise, but I notified the seller. We talked via email back-and-forth and the seller resolved the issue promptly it was nothing wrong with the bike. It was the way I put the bike together . I highly recommend if you want an electric bike that you buy from the seller I was not disappointed at all.
