After lurking and perusing the forum for ideas I thought I would throw my hat in with the following. I live in the middle of a very forested corner of the realm and have access to a life times worth of forestry trails for which I want to ride with a full suspension rig. I had already built a hybrid bike using a Bafang BBS2 crank motor on a 67mm BB bottom shell so had the kit but not a suitable rig. After much research I now found my perfect donor bike a Voodoo Canza 2017 with a bb of 73mm which is fairly unusual as most other mtb makers have gone over to much bigger bb shells. It has a great rolling resistance, superb suspension and additionally a slack steering head allowing easy inertion of a 48v 13ah frame battery mounted under the frame using riv nuts for the m5 mounting bolts.
The bafang motor slipped in easily after removal of the BB shell. Only slight problems being unable to use the metal dust cover over the lock ring on the left crank. Additionally on the drive side the drive chain would not centre. Not a problem just reverse the bafang 48mm chain ring and the chain lines up perfectly. I have mounted a rear rack directly onto the rear suspension unit so can carry panniers or whatever. I have an easy 35 mile range. Should the battery die on me I still have 10 sprockets on the back which combined with all the additional weight being on the bottom means its not too hard to hoof it home using pedal power. Total cost £500 for the Voodoo, £350 for the 500w bafang, £250 for the 48v battery. Total cost just over a grand for what I consider is the almost perfect full susp emtb (roll on new battery technology)...... 200 miles in and no problems to date.
