Re: Lightweight/discrete Q128c commuter build on a road bike

I went DIY tubeless on my 2 WD a couple of years ago and so far, all is good. Admittingly, it took several tries to get them just right. https://endless-sphere.com/forums/viewtopic.php?f=3&t=71203&p=1076342&hilit=tubeless#p1076342 My most recent set-up is Crazy Bobs run tubeless and these days, I've...

Re: E bike Gearing Why Bother

Although I'm on PAS almost all the time(I use the throttle to mount the bike), I rarely shift on my 2 KW 2-W.D. I start w/ the frt. mini(Cute) because it has more torque off the line than the super smooth, but sedate old Ezee V1(It's the classic car of hub motors, understressed and stately). But I'm...

Re: Identify motor help an some questions...

"Can't see the forest for the trees"! It's hard to tell a motor from the serial #, they don't seem to follow any "rhyme or reason". From what I can tell, it appears to be a large mini, like the FX07. If that is the cover side and that line is a seam, it opens like the other MXUS mini's. That is, the...

Re: Cute Q100H Autopsy & Modify 2017

I wouldn't do that. I added ATF to a Q100 several years ago and without dedicated axle seals, it came right out and rendered my disc brake useless. I had to take the whole thing apart to clean out the mess. I don't understand why everyone is so worried about the Q100 "over-heating". On reasonable po...

Re: Disassembling Geared Hub

Well, the motor is somewhat different than the geared mini's I'm used to, but unless I miss my guess, only the flat cover comes off and the rest is a housing. The motor "core" comes out by tapping on the opposite axle, but don't strike the axle directly. Thread the axle nut backwards on til the nut ...

Re: i'm new here and with ebikes, so...

The way I see it, it's usually difficult to "upgrade" a store bought ebike. It's like they don't want people messing w/ the system and, say, upping the Voltage may require replacing everything except the motor. And at that point, it's easier and less expensive to sell it and start w/ a "home built" ...

Re: Best Full Suspension ebike Frames?

No doubt, but we are talking street bikes here where the the worse thing to be encountered are potholes. As long as the first few inches are supple, the ride is good. The thing about air shocks is, the air spring is progressive by nature and even if they are run w/ too little air pressure, they don'...

Re: Best Full Suspension ebike Frames?

More common bikes I would look for would be the Giant Anthem's and Trek Fuel's of the mid 2000's vintage. They all had nice open triangles, but if used w/ a frame bag, they need some sort of guard so the vertical mounted shock doesn't wear thru it.

You ride in space? It's a very general question, so I will give you general answers. Don't buy the cheapest and for "urban" riding, you don't need the latest "trick" bike. The fact you have a 26" wheel, means you can look for a used mountain bike say, 4 to 8 years old. A decent mountain bike that is...

It's hard to make a battery recommendation when you are so vague on what you have. 6T or 8T is generally considered to be a "motor speed" and we might assume that it's a MAC geared motor, there is no way to be sure.

Well, not that much experience, a pair of Ezee V1's.

Yours look like they are still attached. When you the green thingy...

Re: Troubleshoot Mac Motor

trace the "dead" wire to the PBC and peel back the epoxy in that area. It's likely the wire will come off w/ the epoxy.
