What kind of battery do you expect to be on a bike retailing for £500? Cheap no-name 18650s are useless on hills (sag) and have short lifespans. The user experience will be sub par.
Electric motors are a dime a dozen even though they have an expensive metal at their heart. Kalkhoff have shown that German engineering may not be all that it is cut out to be with the gears and bearings of their motors. The Chinese have no problems using beefy bearings and the only people stripping or melting gears in Chinese motors are hot-roders.
I think that the bottom line for reasonable quality is closer to £850 (post referendum pounds...).
