    BionX Questions - Regeneration & Battery Cycles

    Motor rpm limitation is imposed by the size of the wheel. You have a 20" wheel and if you trick the system into believing you have a 26" or a 700c wheel, you are not defeating the speed limiter at all. What you have done is simply telling the motor to keep turning until it reached a set...

    BionX P250 max speed and 36V battery question

    Alan, I would be curious to hear what generation Bionx system you currently have. Mine is early 2008 and as much as I would like to do variable throttle control, it either does on or off and nothing in between. It does however detect terrain and environmental changes (headwind) and react to...

    BionX P250 max speed and 36V battery question

    Alan, you are correct that all Bionx system's throttle control provides a ramp up to the maximum assist speed and this is a smooth computer controlled operation, which behaves like you have a variable throttle control. It is adjustable somewhat in the control panel too. But it is not the same...

    BionX P250 max speed and 36V battery question

    The only advantages of owning a Bionx bike is the fact that it is currently one of the lightest, well packaged and all around ebike retro-fit kits out there. There is a computer that is governing the assist level, which is why the thumb throttle switch provides only an on (full assist)/off (no...

    E-bikes: an extremely unreliable form of transportation

    I had BIG PROBLEMS with ebikes.ca 9C system, especially the wheel and the charger. 1, First they gave me the wrong charger (24V as opposed to 36V) -- what happened if they gave me a 48V?!? :shock: (I take it this is simply human mistake). But is this not an acceptable mistake to me...

    E-bikes: an extremely unreliable form of transportation

    It depends upon your valuation system. There are many prices of cars and homes. A Mercedes Benz is not a Honda Civic, nor is a Ferrari. Is Ferrari a waste a money? Only to those who can't afford to drive it. This is not the case to those who can! Parts for a Ferrari or a Porsche is not...

    E-bikes: an extremely unreliable form of transportation

    It is entry level no doubt, but a typical roadie will have a hard time catching up with me if I pedal and have assist at the same time. I can not compete against someone who's riding at 40 to 45km/h. Besides, he's not riding a bike, he's driving it, so don't pretend you are cyclist. And no...

    E-bikes: an extremely unreliable form of transportation

    Oh my, what are we turning into now -- my rod is longer than yours and my house is bigger than you?!? A typical ebike is as reliable as the person who puts it together!! Charles Bronson once said, "I'm not afraid of the gun; I am afraid who is behind that gun!" I work in the electronic...

    BionX Kit Questions

    Decide on the price you want to spend on and stick with it. You're going to get some exercise regardless of which ebike system you ended up with, so don't worry. Bionx is a luxury system and is not meant to be affordable for everyone either, because of its sophistication on the computer...

    BionX Kit Questions

    As an owner of a Bionx as well as a 9C (throttle type), the Bionx is fun to ride with. The open throttle system is flexible -- you can change anything you want and you get more power. If you are a seasoned cyclists who spins smoothly, go for the Bionx bike. Spinning smoothly reduces...

    BionX Launches Hub Motor with Integrated 3-speed

    Actually, my 24V P-250 is using a high torque motor due to the fact that it is a 20" wheel as I was told by my dealer. Apparently, a Bionx dealer in town used a P-250 and slapped on a 36V Li-Mn battery and rode up Cypress Bowl, which is basically a 10% 10km hill climb. It was on a yellow birdy...

    BionX Launches Hub Motor with Integrated 3-speed

    Undoubtedly, the IGH3 hub allows folder bikes like Dahon which, before the conversion had 27 gears (3x9) though an SRAM 3x internal gear on the rear, to be restored back to 27 gears as opposed to 9. The current only way to restore bigger gearing back to a Bionx equipped bike is to add a Schlump...

    BionX Launches Hub Motor with Integrated 3-speed

    Despite what the marketing people said, the PL-250 HT IGH3 is based on the PL-250 HT, which is a higher torque version of the PL-250 motor. Even the product page on the Bionx site itself said that it provides a higher % of assistance level compared to the PL-250 without the internal gears. My...

    BionX Launches Hub Motor with Integrated 3-speed

    It would be nice if it does. But I think given that it's from SRAM which bought Sachs awhile back and they were known to make the Sachs 3x7 (I used that hub and did 8000 miles pedal power + no problem), it's a hub that replaces the need for a front derailleur. Since this is targeted to...

    Lets be honest, anything less than about 18ah SLA's

    I think vendors sell lower capacity SLAs to compete in price. It's pretty normal to see this not only on the ebike circle, but pretty much any electronic gadgets you buy these days. Many of them provide Alkaline batteries that you know won't last for very long on high drain devices like a...

    Trek teamed up with Bionx

    To get a motorbike performance, the Bionx kit is not it. I have a 9C as well and it beats my Bionx as expected. Is my Bionx bike then overpriced? The answer is a no, because looking at it prospectively, it is a pedal biased electric assist system that automatically provides assist without...

    Trek teamed up with Bionx

    The Bionx bike system is not your average PC version of ebikes as it operates differently in terms of energy expenditure and conservation. It certainly isn't up to snuff on power and acceleration against some of the Chinese made geared or brushless motors available now. While we worry about...

    Trek teamed up with Bionx

    I believe it's based on the new Sin Drive PL-350 with the new rear rack battery/light design. If you want the approx weight, it's the weight of the the normal Valencia + a PL-350. People who are buying this kind of bike is the same kind of people who buys a Macintosh or an iPod touch. They...

    Higher voltage gives you speed on a lower operating motor voltage, this is called over-volting. If the motor needs 48volts to operate at its proper efficient speed, then it needs a 48 v battery pack. There is no speed gain. There is a speed loss if you operate it at 36volts. Voltage is...

    Need advice putting together bike that's good on hills...

    As I recalled from the Ping ebay website, their batteries are rated 1C sustained and 2C peak or is it? Battery voltage is not a true indicator of battery prowness. C rating is, and my NiCad 5C rating works damn good on the hills, being only a 36V. You can have a 48V 10Ah with a 0.25C rating...

    The purpose of the BMC V2 is to go up any hill really well on a cargo bike -- Xtracycles equipped or towing a trailer or even hauling a heavier than usual rider. This is a motor bike motor of motors for hills! I am not sure where you live, but do you need to climb a 22% grade every day to...

    Need advice putting together bike that's good on hills...

    A light weight bike should marry with a light weight electric system. Again, if you plan to ride the bike and have assist, then both the eZee and the Bionx are quite light. And you want a light electric system, because anything heavier will change the ride characteristic of your bike. Ideally...

    'Electric Bikes for Dummies'... aka, I need advice.

    First of all, it's kind of difficult for us to give you basic advice if we don't know what your budget is. Since you're in a fixed budget, this sort of limits you on what you can buy kit wise because the 2 most costly items on the list of 3 are the motor and batteries + charger. Secondly, what...
