DirkB, Trike + cargo ~ 100kg. The trike itself is weights ~60kg. With the single gear, I can barely move 2 lazy kids ~50kg each, so yes definitely would help. The steering aid is viable solution. I am still using sticks for training, so they are readily available for other use. I just need a base tube for single speed bike. Another possible design is to permanently extend the tube high enough to hands level, and accomodate rear mirror, head light, and phone/GPS, like http://www.youtube.com/user/B100Saa.

The solution was to find a stick and put it in the derailleur tube up front using it for steering aid. That way it was possible to walk without getting back pain. > >Dirk > >On 05.06.2011 05:34, Vi Vuong wrote: >The problem with multi-rider cargo vehicle is the space and time the extra >rider(s) would cost, unless the cargo is heavier than one rider can handle. > Electric motor assist is gaining popularity here. >> >> >>Couple of weeks ago, I got leg cramp going up a train overpass, after ~3 hrs >>riding the futon trike, ~200 lbs with cargo to and back from work.
