eBikes

I pretty much only have conversion builds so all I can recommend is ebikes.ca for parts haha, they make a nice field oriented controller (baserunner) with thermal rollback and field weakening for higher top speeds that's super compact and fits in the empty space of hailong-style downtube batteries so it's nice for sleek builds as it's 100% invisible & hidden under the downtube battery, though I have mine hooked up to a cycle analyst display which adds more flexibility for throttle settings.

My dream build will be to get a custom titanium frame from waltly with ebikes.ca's G310 geared & clutched rear hub motor and a bottom bracket torque sensor, but that project has been on hold. Plus I also have an old FlyKly all-in-one rear hub from kickstarter on my road bike so I don't really need another ebike.
