Thanks, corrected it. I had a brochure from them, but it didn't offer much information. Supposedly 50 - 60 nm of torque (seems high for such a small motor), 6.5 - 7.0 ponds for the removable motor/controller/battery unit, and 2.5 pounds for the special bottom bracket that stays on the bike when the unit is removed. This is just what I've been looking for, modest assistance with minimal weight penalty. However, a few reports indicate there are challenges to be solved before the system is perfected.
