I bought a used HPVelotec trike 15 months ago and it came with electric motor and such that I stripped off. BUT, the thing also was equipped with a custom (by Greenspeed) 73x110 chainring. No way I’ll ever be able to use it. So, I’m very willing to part with it. I can see no wear on it but have phone pics I’ll send to any interested soul.  Here’s the kicker: I have the invoice from Greenspeed and it’s for Two of these animals.  Yep, I’ve got the second one also and it’s absolutely unmolested. Also have two ring guards for them.  Custom made and invoice is for $242.00 each. Obviously I don’t want that for them but they are unique. If you’re interested text me. Two-1-four seven 7 zero 43 zero 7.  
 
If no one here needs one I’ll put it on BROL.
