The continous current rating is 5 amps on those packs with a 20 amp peak? Ouch, for hub motors I don't think this cuts it. Reduced cycle times and heavy use...
The more powerful the assist motor the less need for human gearing. However, if the motor increases the speed range of your bike you may want a wider gear...
Back in May I had a spill on my assisted mountain bike at 30 mph and landed squarely on my forehead on the pavement. I was wearing a typical half shell...
So, a crystalyte hub motor with disc rotor won't go in a rear 135 mm drop out ? Even with 5 or less gear cassette ? 20" rim Is anyone using a rear hub motor...
I have been reluctant to tell my story but I never did use a helmet until 3 years ago when at only 17mph not under E power because of the back wind my face...
Todd Are you talking about the Helmets typically used by skateboarders and rollerblade people? I’m not familiar with the term “Full Face”. I like having...
In the Series 4 a disc brake and a 7 speed Mega7 works fine, the 8 speed could work only if you spread the rear forks. Series 5 = Disc Brake and a single...
For city use in stop and go traffic they should be okay, they suck if you floor it and Ride up long hills or for long rides at a higher speed/ Same old problem...
... the ... 10 ... If I'm reading the discharge chart right, these batts might still be useful if your amp draw seldom needs to be above 14-15A for any length...
Good Grief…good to see you are still with us. I would lose the DF and get something low to the pavement. One of the selling features of a recumbent are...
... Long time ago, a friend gave me a Giro Boreas helmet. I wear it every time I ride, except for short trips to the mailbox (500 ft. driveway). After reading...
... Yep ! Same for me, I never wear a helmet until today though I always put one on my daughter's loved head. I'll buy one tomorrow and will wear it each ride....
Hello. I was running three ABF 11AH 14.8V Li-Polymer packs in series to provide 44.4V to my front 408 hub motor. I had an unfortunate incident where the BMS...
Philipp, It looks like 14ga wire has .00297 ohms per foot. The 2 battery wires measure 1 foot each for 2 feet total. 2 times .00297 ohms/ft is .00594 ohms...
Philipp, Yes, ABF have chargers and their construction looks very solid and professional. I have not taken one apart but might do in the future. It has a red...
Dale, The motor is an inductive device and kicks back negative voltage spikes. Resistive loads will not do this. If you analyze the damaged FETs you would find...
After 3 days of riding my buddie's, I would say It should be considered.... I would say it is the Bigha of Pedelects. Well built and expensive. Maybe a good...
Hello Tim. Thanks for the very generous offer and the great advice. I have salvaged some of the batteries, and I am using some of those salvaged to power some...
Dear group, I just wanted to put a feeler out to see if there is any interest in buying a 2002 Currie US Pro Drive conversion kit. The specs are as follows: -...
Tim Isn't there already a flyback diode built into the PWM controller to protect it's FETs and wouldn't this be in the circuit during discharge? Shouldn't this...
I just got back from a tour of Italy and the Eastern Med, and you are right about the traffic. We here know nothing of traffic congestion compared to the...
If you aren't certain the batteries can take the peak power demands, you could try adding an ultracapacitor in there in parralel but that's once more mucho...
Rick, All wiring has inductance. At high currents this small inductance between controller and battery can develop enough voltage to exceed the BMS FETs ...
Hi Joshua, I just wanted to say thank you for our new motor. I really appreciate your willingness to replace the motor on our Currie drive project that didn't ...
... That would be David M. Eggleston and his Alleweder velomobile. He posted recently to the Velomobile list. Doesn't the motor sound a lot like the "Randy...

Hi Josh It would have arrived sooner had I not insisted you lived in Hammond Mass…whoops The windmill idea is cute, harness the wind of the cars and trucks...
