Thanks for the link..

Having done a few e-bike conversions, couple of things come to mind with that system.. The TSR-2 becomes a TSR-1 ... so you have to hope that you can ride a single speed, especially when the battery is dying and you have to overcome the drag of a regenerative hub motor .. having everything in a single big hub is pretty limiting.. battery capacity will be compromised, and heat dissipation with motor/controller/battery in an enclosed space will be a factor.. it's a cool concept, but pretty proprietary for day in, day out real world usage.. a TSR is a great platform for e-assist on small wheels due to the suspension, long wheelbase, and general excellent handling characteristics ..

I like the front hub motor ARCC E2 system much better .. it'll have multiple gearing options, increased range, and plug and play battery options with commercially available, easy to source batteries.. I may do an e- Moulton later in the year .. couple of other ebikes ahead of it..
