Differnce between 250 HT ,350 and 500


I wonder if there is a difference between the 250 HT ,350 and 500 motors.
I mean, is it only the software who is making the difference?
Can we turn a 500 W motor into a 350 motor if it would be possible to change the software?
I see on the Bionx website there is no difference in weight (4,7 kg)

I was on the blower to BionX in Canada a few weeks ago. I was told "I would not notice any difference between the 350 and 250HT". I interpreted that as meaning they were the same. I have also read a dealer's ad on ebay stating as much, "identical to P-350". The comment from BionX was said to me in the context of using the BionX system in Europe, which has a lower wattage limit than America. I concluded from the conversation with BionX the 250HT is a marketing measure to comply with Europe's laws while satisfying customers who suspect or feel the 250 is underpowered. I don't know about the 500, I'm sorry.

Is there someone who opened one of these motors to compare?
We in Europe we have the HT 250 watt. I am quite sure the Bionx HT give fare more power. (more than 250 W for sure )

How can you determine based on the Motor ID if you have a 250 or a 350 or 500 watt Bionx unit?

May be i can provide some insight. A 500w motor is a 500w, you cannot change it by the software. Here are the differ type Bionx motor that are generally not published on the web site:

250w 280rpm
250w 370rpm
250w 300rpm
350w 300rpm
350w 385rpm
500w 480rpm

I don't know much of 250HT, because we can't get them in North America, only special partner that makes bike with bionx system. It is only sold in Europe. I believe it may use thicker copper winding. It is also a bit marketing and breaking the rule. Most of European countries only allow 250W motor, had a speed limited on 25km/h but nothing say about limit on voltage. So the Bionx 250w HT are generally match with a 37v, it give much faster pickup speed, and much higher torque due to 37v instead of 24v, but still limited at 25km/h.

Hi all i am in the UK and looking to buy a 1 year old 24v 250w unit that has the NiMh battery. Any tips to look out for such as how to identify which 250w motor. also i imagine in the not so distant future a battery will be needed so are there any lasting effects in over running the 250W motors on 37V and will the controller handle the extra current?

many thanks mike
