![]() The most common problem I've run into is broken spokes. I think I will be more than happy with the results I have decided to go for a Ping Life4 36V 20AH battery and the 16 tooth freewheel upgrade. I always pedal up before applying power from a standing start and very often use pedal assist.Īll the roads in my area are pretty much level no hills. I am 60+ and I know exactly what its like regarding health and fitness in senior yrs. ![]() With a 36v set up, most Torque Per Watt, (TPW), would be throttle 5mph, mph and Above this optimal TPW range power, usage is reduced, but a growing percentage is used to maintain drive train speed, not put on the road. Logically then, 1/2 throttle would be best, for the 4-6mph range. With 37v & re-gearing enhancements 1 of my present bikes is capable of cruising at 27mph, and 30mph+ with my help, on the pedals!ĭr Kangel - 50+ and getting younger every day!Ī 24v EZip motor, (top speed 16mph), seems to be most efficient in the 8-12mph range at full throttle, at 36v, in the 12-18mph range. With practice, and the determination to pedal constantly, as my health and fitness increased, I upgraded the top speed and pedal capability to continue challenging myself. I first bought an EZip 3 years ago because my heart and body were in such bad shape I couldn't ride a normal bike. But as an EABike, pedal & motor, it becomes a power house, I typically blow cars away, from a red light, takes them 1/2 a block to catch up with me. In other words it is approximately equal to a bikers pedal ability. This is, about the equivalent to the capability of a "fit" biker. Personally I would not classify the EZip-Izips as electric bikes, but rather as Electric Assist Bikes. With a 36v set up, most Torque Per Watt, (TPW), would be throttle 5mph, mph and Above this optimal TPW range, power usage is reduced, but a growing percentage is used to maintain drive train speed, not put on the road.ġmph>30 (tested with 30amp replacement fuse, blows quickly)įull throttle up a hill at less than 5mph. I always attack a hill, accelerating before hill and pedal hard to maintain speed, reducing throttle as speed decreases.Įlectric motors have a range of efficiency.įor example, full throttle from a dead stop might produce 10% power and 90% wasted, (damaging), heat.Ī 24v EZip motor, (top speed 16mph), seems to be most efficient in the 8-12mph range at full throttle, at 36v, in the 12-18mph range. ![]() I always pedal, w/motor, from a stop, till at cruising speed. I've ridden thousands of miles with no overheat problems, probably because: I've heard plenty of stories about these motors overheating and burning up, some have gone to great trouble to add extra cooling. ![]()
