Does anyone know where to buy the crank assy for the hill climbing at Hitech?
I have just sent them and email but was wondering if there were any other souces.
Using it on a tadpole trike means just making a new boom with a suitable attachment point, and having a mid drive means I will still have lots of gears.

Several threads have brought this up, and since theres apparently no drop-in solution you'd have to put together the drive unit. I don't think Cyclone sells the freewheel crank-set by itself. Their system is somewhat pricey, and if someone could buy the freewheel crank at a reasonable price, the rest of the system could be easily pieced together.
Most of the well-recognised fabricators here have commented that they feel a 90-degree drive would have too much friction to make it worthwhile, considering the amount of adaptation it might require. Heres the "freewheel crank" thread from the "resources" stickie.

Once you've got a freewheeling crank, I have wondered about the 90-degree drive head (I also doubt High-Tek would sell their BB-drive by itself). Here's two options for consideration, an angle grinder and a worm-gear saw. Probably some reason why they wouldn't work, just an unresearched thought...

Ah poop, Hitekbikes only sell lots of 100 plus.
On the plus side super quick reply 12 minutes!
If anyone knows where I can get one? its the same as the Panasonic drive I think.

Well, I don't know how much friction there is in my wheelchair motor's 90-degree gearbox, but it certainly works well even so.spinningmagnets said:
It does take about 30Wh/mile for CrazyBike2, but that's for 150 pounds of bike and 150 pounds of me, and other inefficiencies of the whole bike. Also, it's a 4-pole brushed motor, which is less efficient than a good brushless would be. Does work, though, and it fits a lot better mounted longitudinally than the other motor options I worked on before it.
Regarding the grinder, on the ones I've opened up so far (all cheap HF stuff) the bearings are not good enough to last with any real loading on them. I suspect the Makita would be a lot better; I've not had to open mine up.
