Re: SIKK Fat Bike 49cc/MXUS 3000W Build

O and Doc do you think it's absolutely necessary to use both of your TA for the MXUS V1 4 turn with 72V and 18 fet Infineon set to 120 phase amps?

Re: SIKK Fat Bike 49cc/MXUS 3000W Build

Would you happen to know if the seat-tube mounted jackshaft is sold by itself, or only as part of a full gasser kit? I know where your going with this and it has crossed my mind more then once. Mid Drive :mrgreen: All I would have to do is mount the motor on the engine plate and BOOM DONE. I got th...

Re: Help with Capacitive Spot welder

Hope you got this for a good price because the cap and the transformer will still be the big $$$ items after the FETs. Yah he gave it to me like 8 months ago and I still haven't paid him for it yet. :oops: But he said 100 buck would be fine. D20 is a 50A bridge rectifier diode turning the AC to DC ...

Hahahahaha I'm good now. I'm just going to get my cruiser going again right now with those laptop cells, 60V controller, 3 speed switch, 1000w 9c. I'm not sure what wind the 9c is. I had 60v (15s lipo) going though the stock 48v controller at one point and it went 35mph. At 48v (12s lipo) it went 23...

Help with Capacitive Spot welder

I got this kit from someone who built it himself. He said it worked and he had used it to spot weld cells together when he replaced power tool batteries for people as a side gig. I'm a noob to this sort of thing. I was hoping someone might be able to help me get this spot welder going. As far as I k...

Re: Using a lightweight generator to charge Bosch e-bike bat

true true. And the Russians did it that way too. I'm in the states BTW, but same difference. I was just thinking about crossing the desert. Sure you could bring more batteries but these 49cc 4strokes are supposed to get 150 miles per gallon. (I think 100 is probably closer to reality though) And I'v...

Re: SIKK Fat Bike 49cc/MXUS 3000W Build

Yah I'm not sure if I really have to. I wasn't going to originally. I do have a 18 fet Infineon going with it. I think this is a 65 amp controller. I was going to run 120 phase amps with these stock phase wires. This motor is a 4 turn V1.

Many many thought on this subject. I like the debate. For one I cant wait for Air Batteries. No I don't have a link but I read on yahoo news a month or so ago that lithium Air batteries are being developed as we speak! These batteries breath air like engines and are only as heavy as the lithium in t...

Re: SIKK Fat Bike 49cc/MXUS 3000W Build

Got the new freewheel and the only one they had comes with a granny gear on it! Which I like! :D Put the washers on the spokes and centered the rim on the hub the other night. I found out that I can't dish because the axle isn't long enough for the wide dropouts. Now I'm trying to get the freewheel ...

Re: MXUS 3000 Hub Motor

I really like those charts. It would be nice to see a 28" wheel on there as well. For us using this motor with fat tire bike. (I can just guesstimate though 8) ) Anybody know where these wires can be found in the U.S.? I tried to order them but couldn't change the country. :lol: I used "ÖLFLEX® HEAT...

Well I went to the bike shop today and got the free wheel removal tool, but I could not get the free wheel loose! Probably because I've been running around with the gas engine for two months. Every time I shift I let off the throttle, shift, then try to ease back on the throttle, but it usually snap...

painted, drilled holes in rim and test fitted hub a couple day's ago. I just snugged the spokes a bit. I didn't have washers yet. They came today. I dished the rim to the left, thinking this is what is needed to get the free wheel all the way over to the right. Might still have to get a free wheel s...

Re: Ebikeling "wide" 1500w kit

Diggler; think in terms of amps and not watts. If you can find a lower speed winding version of this motor and want to run higher volts to save a little money on the controller, go for it. You may see a little bit more efficiency as well. I'm interested in these motors if you can get a lower speed ...

Re: Ebikeling "wide" 1500w kit

I have seen dyno graphs for other similar 35mm motors. One thing of note is that they were a little lighter. But they peaked out at a pathetic 80% efficiency, which is terrible for a direct drive motor. Even an older 9 continent 28mm will peak at 82-83% efficiency. Right :) An extra 10% efficiency ...

Finally got done capacity testing all the cells that didn't bleed down too much yesterday.

Re: Ebikeling "wide" 1500w kit

yah if you look at my thread they will lace it to any wheel and even upgrade the phase wires to 4mm it's about an equivalent of 11awg for free. This mean that they will put a bigger axel in it so they have to use a cover from a 2000w motor so they said the width will be wider than the 135mm rear and...
