    Bion X Speed

    I notice that some OHM bikes with 500w Bion X systems are quoting 28 mph "with vigorous pedaling". I thought the system stopped producing assistance at 20 mph. Does anyone (350) have any data on top speed of Bion X on flat surface without wind assistance?

    32Km/20Mile per Hr is where assistance cuts out, for both the 350 & 500 as far as I know... By just pedaling you can go as fast as you can pedal... The owner of my LBS here has a 500 and all he can get is 32Km/20mile per Hr...
    He uses statistics as a drunken man uses lamp-posts...for support rather than illumination. I do like my beer, so sometimes I do end up leaning on the lamp-post...

    350, thanks, that's what I thought. It's possible to attain 28 mph on a road bike, but I'm not sure the Bion X motor is providing much assistance at that speed. Too bad since I think the 500w system is easily capable of 28 mph. My 20 mph system is getting boring, but 28 mph would be ideal.

    There is, somewhere on the internet that says they will take off the speed limiter for $100... I am considering it and would probably go for it if it was the code they give you so you can change it at will, but I think you need to send them the console and they do it but then you can't change it back and forth...

    G1nko says it can be done Bionix electric bike controller set up and adjustments Maybe I will go to my LBS and suggest they try it on my bike...

    350 - You're correct; talked to my local dealer, who is reported to be proficient in BionX systems, and he said that 20 mph was max assist for the 500w product although "it pulls uphill like a train". Probably keeps me from considering one since I wouldn't attempt to alter it during the warranty period (2 years, I think).

    @2old. Bionx dealers cannot remove speed limits even using the BBI (Bionx Bike Interface). There are several aftermarket ways to do it. I offer the service for $89. It re-writes the firmware in the Bionx motor and console. It is reversible by updating the bike back to factory firmware using the BBI. Technically it does void the warranty, though I don't know if the firmware change leaves any traces in the system that Bionx would be able to detect once the factory firmware is reloaded.

    If it was switchable at will, back and forth I would go for it... 99% I would leave it legal but that 1 %...

    If it could be switched in a manner that the factory was unaware of (so the warranty wouldn't be voided), I'd get a 500 kit and do it too.
