Uhh,, where did I say 500 pounds up the hill? Or geared motor? Sorry if I wasn't very clear, I only know about what I did, and worked. That was a slow wind 500 w rated DD motor. 9 continent type if you will. And it went 400 pounds, in 26 wheel , and about 1200w max , fine. 500 pounds and the rockies...

I got the impression he had the seat at the bottom on the trek.

The other solution, often expensive, is just get a bent.

True enough, wrong fit bike will give you hand and wrist problems. But so does just getting old. :roll: But yes good advice not to pedal hard much on bikes that are making you pedal bowlegged. That's why I couldn't, or at least wouldn't pedal much at all on those dirt bikes with 7 inch wide battery ...

You can safely flex out the frame another 5 mm to cram in a 135 mm motor. 3 mm per side will not crack the frame, it just flexes it, rather than putting a bend in the alloy frame. So just pick a motor, and give it some grunt to stuff it in when you mount it. Don't get the car jack out, and try to pu...

Re the original question, using the batteries energy to heat it is why your capacity/range is less when its very cold. No free energy in this world, etc. As that battery gets near freezing, it gets terrible saggy, using all its energy up in extra internal resistance. And its costly in watt hours for...

I had off road bikes set up much like Dogs. I did not pedal more than a handful of strokes a mile. Rode great standing up, pinching the saddle between my thighs. I rode it exactly like I used to ride my trials MC. But sit down and try to really pedal, It was too bowlegged for me to do it for say, 50...

Yeah, kind of hard to find people selling their favorite bike. And a bit pricy new. There is a very similar pedal forward bike that is cheaper. The Schwinn Candis. When my garage burned it took my wifes beloved townie. But with the insurance money we were putting a lot of the extra cash into upgrade...

Rad bikes are electric, so not them.

One big motor, and 2000w into it, will get 500 pounds up the rocky mountians. Ben there, done it. Talking long hills, and mostly, they max out at 8%. Short hills get much steeper though. Two 1000 w motors will also do it, but I have not personally built that. It was just so much simpler to run a 530...

If nothing else, a 48 t front ring should fit, or perhaps a 52, if you can find the right one to fit your existing crank. Road crank will likely not have enough offset, and rub the frame.

But a 48t will help, as would learning to accept cruising at 22 mph.

It only takes about 100 miles of pedaling with heavy resistance to recharge a typical bike battery.. Or, you could just pedal 200 miles without regen on, for the same effort. What you want is not regen. Get a planetary geared motor that won't resist while you pedal with it off. Then tow a relatively...

5 inches is wide, but should be tolerable. 6 inches can be stood by some, just depends on if you pedal, or faux pedal, or no pedal. At 6 inches, you will be pedaling quite noticeably bowlegged.

looks good, as the wheel turns rolling forward, the axle will try to rotate the other way, so your picture has the modified TA pointing the right direction. If the nut won't fit in that slot when you assemble it, file the frame down just a bit, till its flush with the torque washer, or stack additio...

First, I'd try letting out the air, and re inflating the tire. You might have the tube stuffed in there funny, or the tire not sitting on the bead right. If there is slime in the tube, then it will do that till you ride it far enough to have the slime spread out better in the tube. And lastly, bear ...

Multiple batteries? I've been very satisfied with Luna's 12ah wolf pack. Its hanging in there fine despite some pretty high amps use. I love the way this one is all sealed up in epoxy, virtually water proof, shake proof, drop it proof. If that's enough for most rides, you could do something else for...

Was in Walmart the other day, and saw a pretty cool dash cam for 15 bucks. The neat feature was it turned on automatically when it sees movement, and then loops the film on a sd card. So all you'd have to do is keep it charged, and put it on the bike each ride. A go pro would be a big hassle, starti...

Yes, make a steel plate that fits inside that recess, then drill a flat sided hole in it for the axle. Drill small holes, then finish with a hand file. The hole needs to be closed, not u shaped. Or, modify a regular front torque arm, giving it the exact shape of the big recess in the dropout. Line u...

Sounds like you may have explained what happened when my house burned. All we know is a battery left on the charger too long burned the garage down. But I have long suspected the bms failed me somehow.

Can't say about the battery dealer. The real problem is the battery itself. I'll keep it short and just say I learned not to charge in my house or garage. Chances are you get no problems, its just the results of a really rare problem that sucks. Mid drive a great choice for a road bike like that. An...

Your best option may well be a rear rack, and mount the battery there. On the downtube, especially with no fender, its not a great place to hang a battery and ride when its wet. A rack can be turned into a fender, with a scrap of plastic, at least keeping the wheel spray off it.

Hmm, interesting. Little disc of lead in each contact, tightening the spring pressure and improving the resistance?

Maybe solder blob on each spring?

Seems like it could be a great thing for those with a pallet of laptop packs.

To clarify some on the above posts. First, you should see some improvement with the new controller, if it has higher amps than the old one. Speed is limited several ways. One is the motor, motors have different turn windings, where a 12 turn motor is slow, and an 8 turn quite fast,,, potentially. So...

You should get close to the batteries stated spec ah when you discharge it at 180w. Even a pretty toasted battery can do amazing good, at that low a c rate. If you get way less, like 80% of stated at 180w, its safe to say you will see real poor performance at 2000w. You will need to come up with at ...

The one thing about an EVG is that the hub motor on it is much louder than most. However, this is loudest when running top speed, at about 15-20 mph. When running more like 5 mph, not so loud. But honestly, don't get the EVG unless you are looking at a hundred bucks or less. Nice frame to put a mode...

I would ride that thing exactly the way it was designed to be ridden. Relatively slowly, in deep sand or snow.

And then for faster riding, I'd get this. Or spend just as much on a superb DH bike, and powerful rear hub motor.
