    New "TSDZ2 Torque Sensor Central Motor"

    With regards to the incorrect speed, I noticed that the "magnet" field in the display settings was set to "02". Should have been set to "01" as there is only one magnet provided for the speed sensor (didn't know you could have more than one). The speed seems to be more accurate now. Might be a...

    Utah bike helmet law

    Is it not somewhat detrimental to your skull to dismount your ebike unexpectedly at 30+ kph? We're not casually riding our step through push bikes through Amsterdam. Ebikes riders need helmets in Ontario, Canada too. The bike helmet manufacturers are living high on the hog here as well. Not...

    New "TSDZ2 Torque Sensor Central Motor"

    I was finally able to try out this motor today for first time. It works real smooth, rides really nice. It shuts off and on immediately when you start and stop pedaling,very nice. Ordered an xh 18 display paired with 36V bottle battery , 18A continuous discharge current (NCR18650PF) I did...

    Suggestions for bottle cage relocator?

    Need to move mounting points for a bottle battery on the downtube. I can only mount it with the pointy part of the bottle down (towards the BB) atm, no room to mount it the other way. Any suggestions where to order one inexpensively? I'm in Canada.

    Can you draw power from charging connector on bottle battery

    Simple question, can I run my lights or anything else from the AC charging port on my bottle/dolphin battery? Can I do same from a soft triangle battery pack? If so, is a fuse recommended/necessary between the battery and load (lights)?

    Compact Field Oriented Controller, ASI + Grin, limited run

    I have the phase runner set up with a 9C rear motor (i think with the lowest winding for a big wheel) running sensorless. Ran the auto set up (set it to 9 KV and 23 poles) and the wheel spins up nicely with no load. If I sit on the bike and push the throttle at a standstill, there is a lot of...

    Any issues with the luna cyclops (http://lunacycle.com/extras/lights/luna-cycle-cyclops-led-light/) brightness, beam pattern, durability? Are they the same as similar looking chinese lights (ebay/gearbest, alie x, bangood etc...). Its plug and play for under 72V. If its truly 1k lumen, two of...

    Motor axle, depth in drop outs

    Thanks for clear picture! Yes I thought of a washer too but thought there may be a greater than zero chance of a safety issue, I just got a180mm mount adapter from my LBS, I can prolly exchange for a 183mm or 185mm for no more money, so that would add about an additional 1.5 (like the washer...

    Motor axle, depth in drop outs

    New picture added to the link above. Looks like the rotor is actually sitting too deep into the caliper, it almost touches the bottom (the bike is upside down so its actually almost touching the top of the brake pad spacing in the caliper). I'm thinking that's too slim of a space for any flex...

    Motor axle, depth in drop outs

    I am wondering how deep into the dropouts should the rear hub motor axle sit? I have attached pictures below of what mine look like after doing some filling. Are they deep enough? https://1drv.ms/f/s!AloGliTn6xHyynocIfeTS-eYireU

    BMSB 09 Bottle battery w/ sine wave have torque simulation?

    Thanks DV, you're very helpful with these bmsbattery questions :). The torque simulation feels good (note however I dont have a non torque sim PAS to make a comparison, or a real torque sensor.), power feels smooth. It seems to be speed limited though, i.e. PAS level 1 will stop helping me (the...

    PAS (Pedal Assist Sensor) installation problems.

    I have a a magnet disk wherein only one side of the disk exposes the magnets, so if installed on one side of the bike Id have to flip it, and there would be plastic between the magnets and the sensor. Does it matter which side of bike I install?

    BMSB 09 Bottle battery w/ sine wave have torque simulation?

    Does the bmsbattery 09 bottle battery (36V) with the integrated 20a sine wave controller (https://bmsbattery.com/ebike-battery/678-36v145ah-bottle-09-panasonic-battery-pack-battery.html) have torque simulation? The associated description does not mention it, however the true "bottle" battery...

    axel width cute Q100 front hub and how to measure axle width

    Am I correct to assume that the Q100 from bmsbattery has a 12mm axle width? Also how does one measure the width of the axle dropouts on ones front fork? I measured perpendicular to the straight sections of my front forks axle slots and it measured about10mm. Will the q100 fit? Bike is a...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I had some points I wanted to confirm about cassettes and frames with 135mm dropouts. I read a few pages back that someone said they fit a 9 speed cassette but didn't recommend it . Am I correct to assume it is because the frame is too stretched? I read that 9 speed cassette would need 145mm...
