Hi ES :) I feel like I have found a decent combo of bike and conversion kit, but I am not sure if they really fit. Apart from the wheel size on the kit and the bike, what am I looking for? Any small things, or large for that matter, that might be easy for a beginner to miss? The 142mm hub spacing i...

I can't seem to connect to the bike using the setup utility. Here are the readings from the PAS setup displays: Setup PAS Device - 4.96V - Basic - Note: The PtDt display doesn't change when I pedal the bike. PASD-> Sensor Type - Basic PAS PASD-> Poles - 12 Poles PASD-> Signal Type - 1 wire PASD-> D...

Thanks for the advice. Maybe next time reduce the levels of sarcasm. Not all people find that acceptable. Helping minus the sarcasm would be great and be a much more positive step towards people's communication with you. I have found better help on this subject from other forums with more professio...

Look at the evidence again. I left the battery charging for 24 hrs. It must be fully balanced. The indicator on the side says it is well charged. My multimeter says it is 55v. That is exactly what I would expect from a fuctioning battery. However, the display says the battery is nearly flat. It cut...

How much range do you usually get Sent from my moto z4 using Tapatalk Here's the load graph from Grin's ebike motor simulator for a bike with rider in an upright position on flat ground. Depending on the efficiency of your components (motor, controller), you can add 17-20% to the watts on the right...

I'm just gonna go with a 72v 20ah cause my awd motors are 60v/72v

Probably a good direction. The mixed bag of voltages and capacities from your posts above won't work.

I have a home built ebike with rear 1000W hubmotor kit. The controller is an older, 48v no name ebay purchase with no current specs. Previous;y I powered it with two 12Ah 6s quadcopter batteries in series, about 44v nominal. Recently, I built a 15Ah 52v battery using (42) 26650 cells in 14s 3p arra...

Typically our ebikes are powered by battery packs, not individual batteries. The typical pack consists of several 18650 cells, arranged in series to obtain the desired voltage (e.g. 13 cells in series, or 13S, would provide a nominal 48 volts). These series groups are then connected in parallel in t...

Lol Ive used those to break DC. lol. Works.

Yup, as long as I don't open it under load, no concerns about frying the contacts. If it ever fails, it's only $6 to replace.

I use a 40A AC single pole breaker as an on/off switch for my battery. Since it's AC, it won't actuate based on current, when used in a DC circuit, so I'm only using it because of the contact ratings. Still working fine after a thousand plus actuations. $6 Home Depot.

"You don’t want to go faster on that bike. Use something with full-sized wheels" "...that bike isn't a good platform for speed" They're not wrong. Enjoy your 18mph for now, stick around here and do lots and lots of reading, then see about building a proper ebike in the future. I know waiting sucks,...

Are you taking the bike on the train with you, or do you have a secure place to park it at the train station?

The blue and yellow of the old throttle looks to be a plain switch, likely used to turn the controller on and off. The TAG/PAS switch from the new throttle should be able to provide this function, if it is also an on/off (rather than a momentary push button). The brown and white of the old throttle ...

Thank you for the quick reply, I just noticed the throttle supplied says 24v on the side. That seems to me to be an issue, does the throttle have a certain voltage that needs to match the controller and the motor?

Can you post a picture of the old throttle?

The old throttle has; 1 brown/white male 1 blue/yellow male 1 red/black/green female The new throttle has; 1 Battery Gauge grey/green female 1 PAS/TAS Button yellow/brown male 1 HAL sensor red/blue/white The red white and blue of the new throttle is equivalent to the red black green of the old thro...

I will be in formal business attire, and IMO suspension forks and/or motocross styling just doesn't mesh with FBA . Not sure what you mean here. Are you concerned about your appearance while riding? Realize that the faster you go above regular bicycle speeds, the dirtier you get, so expect your dry...

Hi all, I have a little e-trike and just replaced the burnt controller with an OEM new one. I connected everything but the moment I turn on the key it starts running continiously and no response from the throttle whatsoever. Is a faulty speed throttle or something my noobiness neglect? Thank you al...

Haven't tested the battery with a multimeter but the specs are posted here https://www.leoncycle.com.au/~140

What is the voltage of your battery pack, measured with your multimeter?

When I test the charger with a multimeter is shows 54.6V. I tested the two fuses it comes with as well.

Does anyone have any idea why the charger won't start charging with my battery?

I'd check the throttle cable connections first. If everything looks good, then open the throttle and look for bad connection. Alternatively, just replace the throttle.

It is not related with the power draw nor the pas/throttle mode. How did you arrive at this conclusion? I know for my KT controller, it effectively works like it’s in speed throttle rather than torque throttle mode, when in the throttle voltage range, and then will cut power and coast when fully re...

If they are the Grin LIGOs, then the BMS is supposed to be smart enough to shutdown the lower voltage battery if it detect too high of a charge current. If it shuts down, you’d need to charge that one until the voltages are closer. Or you could just charge the lower battery to within ~0.1V before pa...

Early model Trek Fuel, when they had straight tubes; years when they just started providing a disc brake option.
The triangle is huge for a full suspension frame.

I can't picture spending the higher cost of a mid drive and installing it on a bike with no suspension. So for close to the same cost, get two used bikes and build one hub bike, and a BBS02 powered full suspension mid drive. Use the same battery for both.

Thanks for the reply. I should clarify I don't need or expect to go 30mph constantly, I'm happy to ride efficiently most of the time. And my commute is actually 15 miles round trip I rounded up to 20 miles for some cushion. I think the 8T MAC and 20ah EM3ev battery are as much performance as I'm wi...
