I just said I'd put this up for anyone interested in doing the same,I've been cycling for years and love my new radwagon 4, it's my first ebike and I haven't been off it since I got it. The one thing I didn't like was the gear shifter and decided to change it to trigger shifters like on the rest of my bikes, but to do this I had to change the righthand twist throttle because of clearance issues with gear triggers on new one. I put a thumb throttle on left and then put the display buttons on right hand side, this allows clearance for trigger shifters, I had already changed the original rubber grips that came on the bike to Ergon GC1 grips(first picture,Rohloff/Nexus option for righthand twist throttle) and now after doing this swap around tonight I will change the grips to standard Ergon GC1,I also cut the lefthand ergon grip down to size to fit the throttle on the grip side of the brake lever bracket, I will do the same with new right hand grip when delivered
