CEMoto E-18-Y Mountain Electric Folding Bike44; Yellow

I have owned a CEMOTO mountain bike (eBay $800 w/ship) for 4 months. and It is a little cheesy, not anywhere near a real mountain bike, more like a mountain bike look, front air shock with no oil dampening, bike works well as long as the battery is fully charged. Bought this to help my commute from charging my Chevy Spark EV at the Chevrolet dealer 4 miles down hill from my house. Have 5 complaints 1.) the power assist is not metered and is full on or off completely. Throttle is a power switch on or off as well, you cannot cruise at half speed for example. 2.) Bike is heavy (52lbs) to load and unload from the car. Also true for most electric bikes 3.) Charger is a piece of crap! burns out just outside of warranty! 4.) Chain falls off sprocket jumping a curb every time! 5.) included headlamp is junk. Other than that a few brake adjustments were required (factory loose rear brake cable clamp) Frame is small for my height of 5'11" but usable, over all not bad for a few hundred dollars. If you want a better performance/lighter bike be prepared to spend a few thousand dollars elswhere
