Whilst there is a tonne of footage of geared bike motors climbing hills there doesn't seem to be a whole bunch of direct drive video builds tackling hills?
My X5304 is a pretty decent hill climber however per volt its not a patch on the BMC as the BMC is a geared motor.
Digging around on Google video (remember that? ) I found a great clip of my buddy Steve Head and his dirt monkey bike tackling a 20% grade on a xlyte 4 series motor, he was running at 72V 30A from memory and it was fitted in a 16 inch wheel, he removed the chain to prove that no peddling was added.
The video is a great example of the power of direct drive motors, Steve shoots up the hill pretty quickly.
I was particularly interested in folks with 9C motors, as I intend to get one in the summer for my missus and it needs to be able to keep pace with the BMC on the hills, so how do you all find it's hill climbing ability? and more so do you have any videos you can post here with the relevant data as well? maybe take the chain off for a test :wink:
Here is the old video of Steve and the Dirt Monkey, loved that bike! not heard from Steve in a long time though it does whiz up the hill though. 8)
