Hello, Today I own an Salisbury LPX (as the only e-bike experience). It is ok, but too slow and not strong enough (because it's legal!). Maximum speed is 22kmh (13.7mph) on flat. 22kmh is not fast, and if I want to increase speed by pedaling, it feel like the motor "steal" all the power from pedals! So my next bike should be an illegal DIY built on an MTB with discbrakes and full suspension. If motor is to slow and weak it should have freewheel. Otherwise its not nessesary. I thinking of a cyclone kit (see cyclone-tw.com), the new 500w with double freewheels, because it will be have good balance, easy to install/remove and I can use the old LPX-battery. The other alternative is a 350W front wheel with regenerative braking from www.goldenmotor.com. What do you think about this? Other options?
