Looks good CD, I've got a stack of 40t cells to build a pac, but planning a different shape.. It's been a while since I've done the measurements (on my large frame LMX) but it looked like I could do a 16s8p in a single pack in a 16 cell long by 8 cells offset stack shape. It may require the...

Three jaw gear puller is how I removed mine CD

Looking at my chain stay clearances, it doesn't look like I can go too much larger, maybe 120t max, before the chain starts rubbing the chain stay. I'd found that 150t on the electric scooters website too, but it has a disc brake size bolt pattern, so beside the problem of being too large, the...

Yeah, using #219. I'm sure there must be a laser or water jet service that could do the job, think I just need to do a bit of research. I have used Rebel Gears in the past to do a custom #25 sprocket. They don't have a listing to do #219 though. Member Toolman2, who lives nearby got some...

Perfect, Nuc does field weakening so potential for a few more rpm if I need it.

The LMX64 belt pulley is about 12" (300mm) diameter, so plenty of clearance for a mega sprocket. I'll also be running the belt drive tensioner pulley that routes the chain so that about half of the motor sprocket teeth will be engaged by the chain. All up weight should be in the region of 35kg...

PS - Finally received my pre-order Nuc 24f, so controller is sorted. Battery will be 16s 8p Samsung 40t. Bike will be mostly used in the dirt, so hoping to wind up the phase amps for climbing steep hills.

10kW sure sounds like the figure to soon for. I can't get to 8:1 gearing at the moment, best I can do is 7:1, preference is to use your 15t motor sprocket to avoid the worst of chordal effects of small sprockets. I've had a couple 105t rocket kart sprockets on the shelf for the best part of a...

i always found my LMX lacking in the HP department, have high hopes shoe horning in the big block will be the remedy :D

Did you swap in the 40mm motor CD?

For those of you who have switched over from Nucular 12F to Silixcon SC controller, do you find the noise from the motor is louder?. I've found that my Silixcon controller the motor is noisy once field weakening kicks in. Wondering if the Nucular makes a similar sound at higher speeds?

Thanks again, LMX is 4mm keyway also. The pulley retention is fairly simple too, no circlip groove, just the shaft bored and tapped for an M5 I think. I'll get back to you with details.

Thanks LR, I didn't realise you did your own motor shafts, that's great. I bought a big block from you a couple months ago, was going to shim the shaft to 14mm to suit my LMX belt pulley, but when I saw you could do 15mm I thought it might be better to bore my motor pulley instead. Just...

Hey LR, do you have any of the 15mm shaft Big Block motors available? Thanks, Brian

Great afternoon out CD, looking forward to the next ride. Good to get in a ride before all this rain we've been having lately :D
