Re: Luna Cargo Frame with TDCM igh

http://i29.photobucket.com/albums/c256/1969genhydro/IMG_3412.jpg I'm using it with the Grinfineon 25A controller and a 14S / 14Ah battery. I opted for 25A to be on the safe side given the power range. Maybe 35A is fine. Anyway, the rear dropouts, although relatively beefy, are aluminum, so for now ...

Re: Luna Cargo Frame with TDCM igh

What a gorgeous build. As for the cops, I would think front-mounted panniers would go a long way to not drawing attention to a front hub, especially since you'd only need something small like a Q100 to boost acceleration. You could even just put a Shimano sticker on it and say its a hub dynamo. :D I...

Re: Hidden Wire Brake Sensor always on

Oh, and just one more question...
Is there a reason why there's only one female connector on the controller side, and not two, (for both brakes)?

Hidden Wire Brake Sensor always on

I've got a problem with the BMS Battery-supplied "hidden wire brake sensor", which I connected over the weekend to their S12S controller. For some reason it's always on, regardless if the brake is pulled or not. I tried reversing it (LED facing up) but no dice. Even with no brake cable passing throu...

Top speed of derestricted 24V assist ebike?

After riding my Q128c build, my brother-in-law has been inspired to upgrade his assist-style e-bike with a simple kit he found online. His bike is the common (read: legal) "assist" type -- a 24V mid-drive system that has a sophisticated PAS (torque + cadence). In such assist bikes, the motor provide...

Re: Possible to change freehub of Q128C?

Hey, that's an idea. Might need to spread the dropouts, but might work.

Oh, and regarding spacers when the cassette is narrower than the freehub, must they always go on the outside of the largest cog? In other words, can they placed between the smallest cog and the locking ring?

Re: Possible to change freehub of Q128C?

No, I mean the freehub. Her bike has a Shimano 7-speed cassette (and a corresponding wider chain). During a trial fit today, I discovered that when that cassette is placed on the Q128 (with spacers to take up the empty space), an extra washer is still needed on the drive-side axle to allow clearance...

Possible to change freehub of Q128C?

I'm thinking of installing my currently unused Q128C hub in my wife's bike, but looks like there might be a complication due to larger freehub. Therefore, I'd like to know whether it's possible to remove the Q128C's freehub and swap it with the smaller one that's on the stock wheel. Both are Shimano...

Re: 800W Q128c commuter build

Had a similar issue when recently installing the very same hub on one of my folders with 140mm rotors. Thought about using a dremel, but that would've meant grinding away most of the inner-side adjustment dial. Instead I got an Avid post spacer set and 160mm rotor, which has the added benefit of con...

Re: Q128C motor not spinning freely

Oh, I should've been clear that by "unit" I meant the caliper unit, not the motor. Should be a trivial matter as this particular caliper is rather wide. All in all I'm very pleased with the motor from a stealth standpoint. It's smaller than expected, and the rotor combined with a 42T sprocket I have...

Re: Q128C motor not spinning freely

That was it, chaps. Many thanks. I used the rotor bolts from the original wheel, instead of those supplied by BMS, as they seemed to be the same length, but on closer inspection they're slightly longer. Crossing my fingers I didn't cause any lasting damage. Anyway, now the only other wrinkle to work...

Q128C motor not spinning freely

My shiny new Q128C motor, built in a 20-inch wheel, arrived a few days ago from BMS Battery, but still waiting for the battery which I ordered from another vendor. In the meantime, after placing the wheel in the dropouts, I noticed that it doesn't spin freely by hand, in fact there's a LOT of resist...

Re: The new Qute Q100H motor

Great idea. I didn't realise they're listed on the simulator. Yes...top speed vs torque. Although a higher top speed is welcome, given the sheer number of stops and starts on my route, I'm learning toward the torque winding. Plus, if I overvolt it, I might have my cake and eat it too. [edit] Just lo...

Re: The new Qute Q100H motor

OK, so I've now decided to get the Q100, but am undecided whether to go for a "H" or "C" version. Any advice would be greatly appreciated. The bike in question is a folder with ETRTO 451 wheels. The front wheel having a through-axle means a rear-wheel installation. BMS doesn't sell 451 wheels, but f...

Re: Cargo Node utility bike

If it doesn't need to fold, what about a cargo fat minivelo like Be-All's BNF 20? According to the specs, those are 20" wheels, but I guess the Kenda tires add a bit to the overall diameter. There's also a 26" version.

Greetings from first-time poster. I was bitten by the e-bike bug a few weeks ago, and after reading up on many makes and models, decided (for now) on getting the Xiongda. I was thinking of getting the model with the manual H/A/L switch, or is it better to get the one with switching through the scree...
