Re: On Trolls - not just under bridges any more

It is obsurd how many people ask that same damn question: "Isn't that defeating the purpose?" It does piss me off, cause I do commute 15-20 miles one way, and I am usually soaked to my chonies. My trip doesn't end at the same point I started from (doesn't THAT defeat the purpose?), and I would like ...

Re: High power RC motor and drive unit production

Great work Matt! I was wondering if you could take some more pics of the other side layed out, and maybe even throw a tape measure (with inches, HAHA) in there so I can get a better idea dimensionally. I am trying to figure out where to mount your drive on my rig, I would like to keep it high and ou...

Re: Drive Belt Help!!

D, As I understand it these outrunners are designed to take alot of amps at a lower voltage. It seems like if you are about to pay $1000 for one of those Pletti's, you should get a full support team that can tell you exactly what the motor can take. And then there is me.... I bought a chinese 295 kv...

Re: Drive Belt Help!!

I wasn't able to get to that HAL, thanks though. I decided not to overvolt to 48, but instead 36 volt. Playing with the calculations, I came up with two options: As per Matt's recommendations I am going 5mm pitch (1/5th inch) with a 9mm belt probably GT2 (is this better?). 1. 13 tooth motor pulley t...

Re: Mounting Gearbox & Motor Aluminum Frame - Weld? Bond?

Hold On!! I thought we were all in agreement that duct tape was by far the most elegant way to mount EVERYTHING!

Re: Drive Belt Help!!

Basicly I have been playing with SWBLUTO's ebike calc. and from that I calculated that with my motor a 32:1 reduction will be the best balance of range and speed. With my roller tire combination I get 20:1. Am I correct in saying that when combining 2 reductions, the effect on final drive is multipl...

Tyler, In your previous design, I meant that if you slipped the adapter over that "petal" pattern in the red anodized 8) hub, wouldn't most of the stresses be transfered here? Then just use some spacers and bolt the chainring to the disk and adapter for proper alignment. Hangdog, Glad to have you he...

Re: High power RC motor and drive unit production

I think something like the sheath on this cut tool would be nice for the lowest link, or around the motor. The cut disk is 3" and the whole tool only cost $10 at Harbor Freight.

Re: Left side drive brake options?

That adapter should be perfect TD. The mount on that hub seems to be very similar to mine, I bet it is universal, I will ask my LBS tommorrow. Could you just slip the adapter over the hub, and then secure it laterally by mounting it with spacers to the disk? I wonder how strong that would be.

That's an excellent question John. I just figured I could go to the voltage capacity of my controller, which is 50 volts. Maybe I should gear it to run at 36 volts instead, and just push more amps. I wonder what voltage CNCAddict will recommend for his motor? I know alot of people aren't gonna be ha...

Then imagine bearings pressed into your handlebar, then inside the bearings a steel shaft that turns freely inside the handlebar tube. Now mou...

Re: Left side drive brake options?

TPA, That sounds very complex and different for every disk. Are you wanting to mount on the other side of the disk because the extra material from the sprocket would cause alignment issues between the disk and the caliper? ...breath... If so, it would seem easier to just shave down the disk mount to...
