Re: New Cute Q100 replacement? The Q140 CST

I just got the M140 from elifebike.com and I can safly say that this is the first and last time I'll buy anything from them. First off I got a mail saying it will cost $75 extra to ship the motor and rim if they lace them together for my. I'm thinking thats OK as it means I don't have to lace it and...

How is the torque and speed of the new motor?
You have to give me a few more days. The motor hasn't arrived yet. According to FedEx it wont arrive until Friday, but it arrived in Oslo yesterday so I expect it here sooner. I'm guessing the torque and speed will be the same as the Q100.

Re: What/How to upgrade from my 48v 20a (1000w) ebike

I don't know much about the original GM 1kw motor, but I did a build with a MagicPie3 where I upgraded the phase wires and connected it to a 18Fet infineon controller and 24s LiFePO4 (72v). That combo gives about 4000w to the motor. That bike is very fast and is used every day by the current owner w...

Re: Which version of cycle analyst for Magic pie 3?

Good luck with your Magic Pie. I would recommend CA v3 if you ever want to over volt/amp the motor so you can keep an eye on the temperature (requires you to install a sensor, not too hard to do). You need to buy the standalone version with shunt unless you are going to use an external CA compatible...

Re: New Cute Q100 replacement? The Q140 CST

I don't think it will be a problem (especially with large wheels). Its only 2.5mm each side and you would have to have an unusually stiff frame not to accommodate that. Thanks. I just tested the "springiness" of my frame and it looks promising. So I ordered a QQ-M140-R one plus a 350w min...

Re: New Cute Q100 replacement? The Q140 CST

Most frames will easily spring to 140mm, so it shouldn't be a problem. The only ones I've had difficulty with are frames for 20" wheels, which are relatively stiffer, but , even for them, to spring them 5mm is not difficult. I hope this applies to alu frames too? Mine is 29er so I guess it's s...

Re: 8Fun CST 250w and 350w, what is the difference?

Sorry to wake up this thread again, but I have a follow up question. I have just bought a new bike (Giant talon 29er) with a 10 gear Dyna sys rear gearing. Will that fit on the CST? From the specs I could find on the Internet the 10 speed cassette is 1.8mm wider than the 8 speed cassette and this ex...

Re: Cycle Analyst V3 preview and first beta release

I might add that I personally wouldn't mind if the Trq+Thr mode worked like Trq Cntrl with just the PedRqdSpd added as long as throttle doesn't work without pedaling if I set PedRqdSpd =0. If that makes it easier to program. I imagine that combining those modes would save some programming lines. It ...

Re: Cycle Analyst V3 preview and first beta release

If you set PAS->PedRqdSpd to 99kph then Trq+Thr would work exactly as Trq Cntrl , wouldn't it? Making the old mode redundant. if Below PAS->PedRqdSpd the controller is driven with a level that is the greater of the throttle level or a power level proportional to the amount of human pedal torque.

Re: Cycle Analyst V3 preview and first beta release

What I meant was I would like the torque sensor to also work in the >6kph mode, not just the throttle. (The torque sensor works perfectly when using the torque mode, no complains there). If I understand it correctly the >6kph mode will disable the torque mode? I guess I'm asking for the >6kph to be...

Re: Cycle Analyst V3 preview and first beta release

Instead, the function RPM Cntrl should enable the throttle but OVER THE FULL RANGE , and not just 'full throttle'. Only if the rider pedals, the throttle should become functional in this mode. Please Justin, change the firmware to this point, or this feature is useless to European riders. I have be...

this is what heath talked about. the windings are for specific range of output voltages. looks like you will have to use a 24V power supply in series with the 24V charger. Ok. Bummer. Too bad I don't need a 36v charger though as that seams to be in range (without testing with load). Hooking up a 24...

Re: Converting 24v charger into 48v charger

I took a new reading and waited for the caps to get charged and the R32 started to slow down at around 9kohm, and the r9 at about 5.9kohm. They might go even higher if I wait longer.

R32 is paralleled with a capasitor so I can't get a steady reading without taking it out, but the colors look identical. I can't get a steady reading of R9 either.
