Re: Long tail cargo bike build

If you put springer forks on the front end of a cargo bike you will need to figure out a way to make them adjustable. I have a Surly big Dummy and the first thing I learned when fully loading it was that the front needs to be a little heavier than the rear otherwise the handling gets a bit screwy. I...

Re: Surly Disc Trucker Build

Marks said "geared motors make noise" WRONG! Try one of the Q motors from BMSBattery.com along with their torque simulator sine wave controller. Absolutely silent, all you hear is the tires on the road.

Re: Lost a new ebike off bike rack last Saturday Feb 16

I did make a lost post on the Yuma Craigslist offering a $100.00 dollar reward. Since it was a $65.00 used bike, a $70.00 motor and a $30.00 controller any more than that would be silly. Fortunately the battery was inside the van and not on the bike.

Re: Understanding and Using EGO Power+ Batteries

I just finished building a bike for my neighbor with a Q100 hub and a 7ah EGO battery. I bought a used charger on EBay, gutted it, hid the controller inside the charger case and mounted it on a rear rack. It works great and makes a clean installation with all the connections out of site. The only pr...

Re: Battery problem

The BMS will shut down if one of the cell groups drops below 2.1volts. Check each of the cell groups to see if one group is lower than the rest. If so, manually balance the pack.

Re: Ebike power cut-off due to controller

Battery sag. At higher speed or on hills the battery voltage drops below the 20 volt low voltage cutoff limit of the controller and it shuts off. At lower speed the voltage doesn't drop below the LVC level.
You need a higher capacity battery.

I honestly don’t know at what level my low voltage cutoff works. When the 14s battery gets down to between 47 and 48 volts the performance is so sluggish that I stop and recharge.

Re: thumb throttle for cheap Alibaba E-Bike

Your best solution for lighting without taking the chance of smoking the controller would be to purchase a dc/dc converter and go directly (with a fuse) from the bike battery and put a switch on the handlebars.Search lights and converters.

Re: Found an incomplete ebike at a thriftshop

That is a 9C or a 9C clone which can be a pretty fast motor and be used at fairly high voltage. Where are you located? If you were near me I would be happy to bring a battery and controller to test it for you. I’m in Arizona.

The actual speed of the scooter in question is more related to the battery voltage and the output of the controller. Increase the battery voltage within the limits of the controller and increase ...
