Well I've hit a snag and need the input of some experienced builders.
I've recently finished building a luna cargo fat bike with the LR big block, powered by the 60v, 25ah Luna Battry and the Lyen 65 amp controller. Had a 52t front crank going to the LR big block and 16t to 16t Motor to rohloff sprocket ratio.
I had bolted the Torque axle plate of the rohloff to the rear dropouts of the frame (no room for torque arm).
I went for a long test drive today, by the time I came back the rear dropouts of the luna were completely bent out of shape due to the torque plate of the rohloff. Had I ridden a few more miles I probably would have had a huuuge accident after the rear wheel left the bike.
I bent the dropouts back into shape (took lots and lots of effort) hopefully they are not cracked or terribly weakened. I ordered the rohloff monkeybone and corresponding axle plate. But I am wondering if the sheer power that can bend those beefy forks as much as it did, will not simply snap off the disc brake bolts.
My questions are the following:
-Anyone have experience with the monkeybone from rohloff and lots of power? Is it sturdier than what I had done before (bolt the axle plate to dropouts?
-Anything to check for at the rear dropouts that I bent back into shape? Don't want to ride a weakened frame.
-Any solution to further strengthen rear dropouts?
-Any alternative frame suggestions to replace the luna frame but keep the huge battery/motor/fat tires?
Any pointers would be great.
Thanks
