After I sold my Marin with BPM motor. I'm now back on my 2 year old San Eagle. To remind you, it started like this at about 25kg
and then I fitted a BPPM motor and after breaking the forks and replacing them with downhill type, I added another battery and various other bits and the weight was upto 29kg but it went pretty well.
Then I swapped the motor, controller and batteries onto the Marin and they went with it so i was left with the old motor and frame and the now rather oversize forks for the small motor. I found some old Marzocchi bombers in the shed and managed to fit them and after filing the 9mm drop-outs I got the motor in and added a torque arm from Cyclezee via my friend Dave. I then mounted 4 packs of 22v lipos on the cross-bar which makes 44v and 10aHand soldered the shunt to get 20 amps out of the controller. That gives just about 1000watts of power. It now only weighs 20kg or 18.5kg with half the battery for 5aH and it's very fast and gets me up the steepest hills with minimal effort. I haven't got a speedo, but I'm sure that the top speed is about 23 mph. This is now the third version of my bike and I'm really pleased with it because it's fast, powerful and light, and much easier to handle than my Marin because it's closer to the ground and not so far when I fall off, and it didn't cost much. The only thing I need to change is the gearing because I can't pedal fast enough, so I'm looking on Ebay at the moment.
While I'm here, I just want to mention the Bristol show. I tried a Bosch drive, the new 36v Panasonic and the E-motion Neo Cross. The Panasonic was the least powerful and had a strange klunk when you touched the pedal, the Bosch was OK, but the E-Motion was easily the best for effortless hill-climbing up that hill and it was very smooth and predictable. Everybody should try one before getting too excited about the new crank drive bikes. And if Funkylyn reads this, Dave says tell her that his motor is OK. One of the connectors to the motor had come a bit loose and now it's fixed.
