I wouldnt even bother man, seriously!
For that kind of money, buy a normal bicycle either used or new from a brand name manufacturer then you know its great quality and will last a long time. Why bother having an ebike look like a motorcycle.
You can buy a really great bicycle used for a great price and spend more money on the motor and controller and battery.
Go to pinkbike.com in the buy/sell section and buy a quality used bicycle!
or go to your local bicycle store and buy, even take it for a test drive, get a custom fitting, great service, local.
Think about this, brand name bicycles have engineers design and build their bicycles and them brand name bicycle companies spend loads of money on everything they do, research, testing. What do the Chinese Clone companies do, well they just want your cash and nothing else.
