    New Bafang Crank-Drives

    Bafang will launch BBSXX motors with torque sensor at Eurobike. Im not going this year, so perhaps some one can go and check it out and ride it and give a report. Last year they were in the Zeplin hanger.

    Looks like US production of the adapters is about to start. The manufacturer will set the price, heres hoping its less than shipping them from NZ. Once a few have been made and approved I will release contact details of the new supplier.

    The Bafang intergrated bottom bracket is still in development. It is a torque sensor motor 250w. Aimed at the European market to compete with Bosch. Im not sure you are going to find it available through a second party for a while yet. Aimed at OEM.

    Giant DH Comp Drop Out adapters and conversion

    Is there anyone in the US that wants to take over the manufacture of the DH comp adapters? You need to find a good metal shop with laser cutter and stainless welding facilities. And a fastener supplier for bolts and washers. I will supply drawings and specks. You could pay me a few $$ for each...

    Power Tool Backpacks. 20ah!

    I have now seen a couple of power tool companies putting out 36v 20ah Li-ion back packs. Seems like a sweet solution for full suspension bikes. I wonder what the discharge rate is. Anyone looked into these?

    electric trial bike

    I have a Kuberg trail x. Its not that great. Oset is much better. Kuberg is a primitive bike, needs a lot of modification to make it a good ride. Stock rear suspension is way to hard, tire spins on rim, chain falls of if not perfectly in line, control is abrupt, even on slow settings, handle...

    Ha. No comment. Yeah I'm back. Going to Aus bike in Melbourne this weekend. I have some adapters in stock. Slightly revised, easier to make for me, weight reduction, clearance for the derailer, and captured nuts for the clamp bolt. My DH comp is for sale for any one in NZ. There is a NC8x8 24"...

    If you run one torque arm, you put all the load on that one, stressing the axle out on one spot, running the risk of shearing the axle, if you run two you half the load on each side of the axle, reducing deformation of the axle. I would go for 2 if you can.
