I was'nt dissapointed with the bomber, it is an awsome bike, but it does have a very heavy back wheel, i just thought i could do better for the more technical type of riding i like to do
With DD hubs their limit is easily found on the trails, wheel rotation is often too slow to make good power and they are heavy on the watts in these conditions, a 20" wheel is an option but the tighter radius doesnt ride the rough as well as a larger one so it had to be a midmount.
I have to work on the throttle responce on this bike, it comes in a bit too fast to confidently use the lower gears on rough ground, the new chain rings should help aswell by reducing the squat which emphasises the problem, i have adjusted the shock mountings and settings this morning which has helped aswell.
I am in Derby, very close to loads of trails, a friend was the derbyshire TRF group runs organiser so i have access to all the maps of the country but i know most of the derbyshire stuff by heart anyway. We have done some awsome rides in the peak district, yorkshire, the lakes and wales over the years, we even had Blez come and stay with us who did a feature for Trail bike mag on the peak district trails (TBM issue 57 may 2000) he also did an artical on some baffles i made for the DRZ.
Yes electric for the trails is what i had in mind as loads of them have been TRO'd round here. With what i learn from this bike i should be able to make my next one even better, lighter in the motor department, more powerfull but similar overall weight carrying more batteries. And i will take into consideration cost effective production when designing it.
A few more pics cos i have them
The left side of the motor showing the new bigger O/D alloy spindle with larger seals and a spacer to protect the upgraded phase wires;
The right side showing the out rigger support bearing inside the sprocket carrier, side cover has the thread changed to L/H 30x1mm so it tightens when the motor is driving with a southpaw (lefthand) bmx freewheel (Ground down from 1/8" to 2.00mm for the 7 speed chain)
Pedal crank spiders have been used as the torque arms/motor mounts.
