We’ve covered weed whacker bicycles before and you can even buy 66cc conversion kits now. [geoff390] posted a few videos over on YouTube about another motor option.

strobit (Custom)

Strobit looks like it could be a project to keep an eye on. The entire project is open source, including the hardware.

Development is still ongoing but it looks like they’ve already implemented some mesh networking similar to the zigbee systems.
