BMX Bike Maintenance : How to Make a BMX Bicycle Free Wheelby eHowSports9,115 views
very nice, it my basic design . because you have used the five bolt sprockets your inner ring is too big and your geer ratio will burn the clutch out on your motor too fast. go to a four bolt system so your inner can go down to a 22t. much better for motor

@thescooterguy Thanks scooterguy. I looked at yours as well. They are actually quite different. Mine is designed for an electric motor so there is no clutch. Also mine has 2 freewheels linked together in the assembly so the bicyclist can pedal without turning the motor as well as run the motor without the cranks turning. See my other video with the prototype. The ratios are pretty good for the 350W emotor I use.

Could you tell me where you bought this?

@Mracer2012 - It's my own design, a takeoff from several others. I bought most of the parts from SickBikeParts and Cyclone. The 2nd freewheel is an ACS Southpaw and I had a few parts fabricated locally. I've described the design in more detail on some of the ebike forums. PM me if you want those links or more info

Is there a kit or something that will let me do this? I had the same idea for electric bike drive, but couldn't find anything.
