Thank you, just knowing that the parts are compatible really helps!, Now to design a frame.....

I may be asking a silly question, but I can't find any builds that answer it, does running a cyclone/gng/LR style mid drive reduction kit apply torque to the sensor of a sempu BB and render it useless, or does it not? I want to have my cake and eat it with a 2000-3000 watt mid drive that also...

If anyone can tell me the gear ratios of this hubs igh I may be putting one on a legacy surly troll as a commuter/mule bike

I would highly recommend a dd hub Iver the bbsxx series for commuting, I've had a bbs01 and bbshd, both were a nightmare, atheist once a month I had issues after the first 4 months of use, especially the HD, first my motor shift bearing, then the clutch, plus you can't leave it anywhere, and on...

Can the logo bricks be charged as one homogeneous pack or must the be charged individually? Also, if they could be charged as one pack, could they be wired 4x1 for use on the bike, but charged 2x2 to decrease charge time? And can they be plugged together with varying levels of charge without...

Woodlandhills, I know sturmey archer do a 3 speed hub with sprocket teeth on the hub shell meant to be that jackshaft to a tricycle rear axle/diff, same internals as a standard Sa 3s hub, should be able to take the strain of a 3kw cyclone motor, but at this point I would run a basic cyclone...

I love it, but I'm in the UK and shipping would be prohibitive (I'm cheap) but I love it! The only modification to the design I would do is extend the chain and seatstays enough to accommodate up to 29" wheels, the clearance looks wide enough to run fatty, but it would allow more...

Any chance of a progress report on the sa 5s igh and bbshd combo?

This is the concept pic that i saw

I wanted to see if anyone has any experience mounting two smallish bottle batteries to one frame, one inside the triangle and one bellow the downtube on the underside, this would be on a rigid frame so tyre clearance is doable, I found an image years ago of a mid drive concept called the...

Sorry for the necropost, but how did the porucho fair? Was it comfortable to pedal or a nightmare? Or did the build evolve into a different bike altogether? I'm looking into my own porucho bbshd headway cell build, I plan on a build thread, when I can afford to buy the first parts :oops:

Your best bet is to measure the outside diameter of the bb shell and the outside bb shell of a standard bsa (the usual British threaded) and calculate the difference, if you do this you can measure the distance between the bb and motor casing on the bbshd and determine if that number (plus the...

Ignore the freewheel question, I goofed and forgot that by freewheel in the rf5 description it means rim brake only, same internals as the rk5 while the rk5 has a disc mount. I was wandering how it shifted under load, or if you used a shift sensor? I thought about making a clutch using the...

Hadn't thought of that, one thing I've found is there is an rf5 as well, does the rk5 freewheel when backpedaled? (I know the bbshd won't allow backpedaling but I'm worried that coasting downhill ona fixed hub could damage the motor forcing it to turn unpowered) or am I missing an obvious...

Really sorry to hear about the collar bone! So the cog drives it is a different size than standard sturmey 3 speeds, I can take that into account, possibly machine an adapter for tiny raceface narrow wide chainrings. I hope things he's up soon! Might want to go with a more flexible handlebar and...
