Looks good, I agree on putting the motor on the inside. I would be afraid to clip it on something buzzing around. It would be nice if you could incorporate some suspension but it would require a complete design overhaul. What size wheels and tires are those? I like them. Carl

I think it's a pretty good product and I admire how you guys are handling the marketing of it. There are way too many out there that say it will change everything and it's green, bla bla bla. Go on merit and design alone, if they choose it because it's electric (green) that's their decision. I'd...

This thing is awesome. Do you guys have an estimated cost once you get into production? Great work Carl

Sounds like everything is working good for you. Need some more videos of the system in action. I'd really like to use a system like this but I'm afraid the MAC may seem out of place and too large for most of the bikes I'm looking at. It would be interesting to see the difference between the MAC...

Looking great man, glad to see that your life is on the mend from the past few weeks. We have all been there in one way or another. Those are some impressive trails you have there. Hell I woke up to an inch of white crap on the ground this morning, doubt I'll even be out for a hike today. I...

It's looking good. It will be interesting to see how well it works. What kind of freewheel are you going to use on the crank? It's going to have to be a pretty stout setup for the torque of that Mac. Carl

Way to go, I've been waiting for some updates. I figured that with holidays you've been as busy as the rest of us. Can't wait to see it all together and running. Carl

Sorry no plasma, laser or waterjet where I work. We mainly do stuff out of bar stock and the way we do plate material is less than efficient. The cost shouldn't be too bad getting it cut on a plasma table or even a waterjet for that matter. The brackets shouldn't be too complex to cut out and...

The more I see this setup the more I'm in love with it. I was thinking that for frames this normally wouldn't fit in would be to cut the down tube out and reinforce where you cut out with steel and some good epoxy. It would get the motor back and make it look cleaner. With the right mounting...

AJ, I think I found the thread where Timma tried the Bane Bot reduction. It seems like a lot of his text is missing. From what I can gather he was running a fair amount of power through the gearbox and possibly using a HV160 which could tear darn near anything apart. To keep on topic I would say...

ThePronghorn, nice Find on the BaneBots Planetary Gearbox. I didn't think I could find that much reduction for that kind of price. Awsome!!! Carl

Around 5 inches is all it is? From what I could gather the spoke flange holes were at about 6.7" diameter. I didn't think it could go down that far, but I have been wrong many times before. I've been trying to find detailed dimensions on the Mac but not having much luck. I can't wait to see what...

How is the progress on your trail drive coming? I like the idea of mac ran through the chain, quiet and powerful. How big is the diameter of the mac minus the spoke flange? The front tire does seem close to the motor, I don't see it hitting but other bikes out there may not have enough room to...

Those planetary gearboxes look nice. I've been looking for some and prices can be painful. Those seem pretty reasonable. I have found a few that are cheaper in a nema 34 flange mounting in that 90mm size. http://www.kelinginc.net/CNCGEARBOX.html The specs are a little lower but unless you are...

Well considering I don't want to tear things up too much on my first build I think I have to keep motor speed below 7k. I should be able to hit close to that with a standard the small standard Kelly. Is the sk3 6374 a 12 or 14 pole motor? I thought they were a 12 pole motor which could give me...
