Gocio 500W Electric Bike, 20" Folding Electric Bicycle for Adults, Max 19.8mph City Cruiser Ebike, Electric Hybrid Bike with 48V 7.8Ah Removable Battery UL 2849, 7 Speed for Adult Men Women White

This is my first e-bike and I’m loving it. I’m not going to lie, it is heavy but it’s sturdy and has great power (and it folds). It was well packaged and it’s bigger than I expected. I’m 5’7” and I have the seat almost all the way down (it’s that tall). The instructions weren’t great due to the English translation being a bit choppy but there is a QR code for a video of assembly. (I would recommend putting the fender and headlight on first and then the front wheel, the video tells you to put wheel first then bend metal on fender to fit it through then bend it back). Anyway, between the instructions, picture diagrams and video, you will be able to figure out the assembly easy enough. I was a little hesitant to buy this one due to a couple reviews stating the battery would not work. I think this has to do with the key. The key has to be IN the battery and turned to the ON position (it doesn’t mention this anywhere in the manual), then you can turn the bike on by holding down the power button on the display screen for a few seconds. Also another review said the power assist was too jerky, I didn’t think it was that bad but it will jerk a little if you’re in gear one and power assist is on high (mode 5). It is a lot smoother though if you’re in the higher gears -or- if you turn down the power assist to mode 4 or 3. This bike is so much fun and I’m so excited to have found something that gets my teenagers outside and off their phone’s (I let them pick their own e-bikes). I would definitely buy this bike again.
