Hey All...
I just wanted to put up some pics of my latest project. I bought a Greyborg Frame from Jeremy at Greyborg USA(very nice guy) along with the Cromotor, Schlumpf Drive. Had him lace the wheel into a 24 inch wheel. I ended up using the Cro in a Raptor I was working on and put a Crystalyte 3500 watt motor laced in a 26" rim. I am using a Lyen sensorless controller powered with a 72volt 12.5 amp hr battery from High Power Cycles. Thinking of bumping up to 108 volt though.
The bike is pretty fast when it needs to be but I have set the Cycle Analyst to keep power below 25 amps to go for distance and not speed. It climbs well and encourages pedaling. Thie pics show how I used plastic Push In Rivets to keep the cool panels in place. There is a tool you can buy to remove them for like $25.00. A bag of 25 rivets was only $3.00. The battery is held in place with Velcro. I mounted the keyswitch and charging jack on the left side panel. I think it is very clean.
Still need to figure out a kickstand. Would love to here from one of you about that. I went with a Rox Shock Air shock in the rear and i pretty much have to run 300 PSI to avoid hitting the pedals when cornering. Went with same brand up front. Brakes are Avid Hydraulic.
To compare it with my Raptor, i would say the Greyborg is more of a "Bike" and the Raptor more "Motorcycle" The Greyborg is a very nice designed frame that is easy to pedal and can actually be ridden as a bicycle.

Re: Greyborg build
The rivets are permanant, but there is a $25 tool to remove. They are very cheap and fit the holes in the frame perfectly.

Re: Greyborg build
Look into rivnuts. Those screw in tabs I installed give the same result though. You have to at least own it a week before you can complain about removing the side covers all the time haha.
That Greyborg looks great. What weight does it come in at?
