Mcezdy Waterproof E-Bike Conversion Kit, Includes Display, Control and 500W Moto - Powerful 500W Electric Bike Conversion Kit for Adults with Temperature Control

Couldn't even try it because:1.) Once we received it, we found that it was meant for really thick bike tires. The description says you can convert "virtually any bike into an ebike" and states in only one place that it's used on 20" wheels, but nowhere does it say it's needed on any necessary tire width. We even took it to the local bike shop, and it's impossible to be used on a standard bike tire width and the work we would have to put into converting our bike to have thick enough tires to use this on would be super expensive.2.) This came with no instructions whatsoever. You are supposed to take all these pieces and parts and just figure it out. Totally useless without instructions. We are returning for a full refund.*side note: they also sell one without a temperature control for the exact same price, but give no explanation as to what this does, which I think is not right. First of all, it should be SIGNIFICANTLY cheaper without the temp control because of my second point, it's nearly useless without the temp control. They should let you know that without the temp control, the motor will overheat frequently and require long periods to cool it down, which isn't exactly feasible for many people to just stop. So they shouldn't be the same price and they should be forthcoming with this info.
