  • Best bike for the price!
Color: Classic Black
The bike arrived within 5 days. I was able to assemble it within an hour. The bike lives up to what is offered: it exceeds 37mph, I commute to and from work(22miles a day) on one charge, and the handling is easy! It is definitely worth the price. This isn't the first Ebike I have bought on Amazon, but it is the least expensive with the most value. Customer service is very responsive and they helped me with questions about assembly fast. I definitely recommend this bike to anyone looking for a quality commuter or off-road excursion! ... show more

Reviewed in the United States on August 22, 2025 by Bought this vest not knowing the maker of seller but the price was right. Didn’t know what to expect. To my surprise I received a very nice, high quality, designed and made best. Better than me previous Carhartt vests. I recommend them!!!

  • Street legal? Likely not.
Color: Beige
I just got the bike 4 days ago. It is very solid, bright headlight, brake light with turn signals. The style is nice and very comfortable. The only thing is the speed is 30 mph with throttle only, and 32 mph pedalling as fast as you can. I contacted the company thinking there was a speed limiter, but there isn't, so fastest you'll probably go on flat surface is 32-33mph. You may need to register, insure and get a motorcycle license. Since it is more than 750watts, it is not street legal until you do all that! I'm taking my chances until I get pulled over and say I didn't know. ... show more
