Ampedbikes no longer uses Golden Motors brushless hub. Ampedbikes said he has his own motor and wheel manufactured for him to his specs. I just bought a kit and was happily suprised at what I received. My shiny strong wheel and hub motor is impressive. The installation on my old Specialized Hard Rock (a beloved antique) has been a little challenging. Lots of grinding to fit the wheel into my forks, etc. I have fairly new Shimano gears and shifters, which incorporate the "all-in-one" design. This is not compatible with the motor cut-off brakes on sent with the Ampedbikes kit. At present, I have both sets of brake levers on the bike and might disassemble the Shimano brake levers (punch out the fastener holding the brake levers in) and just use the ampedbike brake levers. Still have to finish hooking up everything. After looking at recommendations from ampedbikes and from this thread, I bought a battery (lifeP04) from PingPing. Stil have to put on connectors that work with each other, etc. Still waiting to finish so I can ride the amped bike. Any suggestions regarding the brake levers? No one is going to steal my old bike with the double brake levers, at least.
