That’s incorrect.

The bionx motor will kick in below .5 mph. The “boost button” is just a throttle that can allow you to drive the bike without needing to pedal. We’ve never had it enabled.

Actually, I was right. Bionx calibrates its motors so they won’t kick in under the set speed, which is 2-3mph stock, but can be set as low as .5mph. Lots of sources out there if you Google it, like this one http://m.nycewheels.com/?url=http%3A%2F%2Fwww.nycewheels.com%2Fbionx-owners-manual.html

And yes, boost button is a “throttle” that turns the motor on full. It helps with grinding because if you do end up in a too big gear on a too big hill, instead of grinding, you hit the button. You can still pedal to downshift. Seems silly not to enable it.

Wait, isn’t anybody going to challenge Bruno’s amusing assertion that kids sit as still as sacks of potatoes??

Well…in practice I had the motor kick in this morning at .3mph. The third party resource you cite is incorrect (and misspelled). “To insure [sic] a smooth departure, the assistance will only start when the bicycle moves at 2 mph or more.” The official manual doesn’t include any reference to a speed at which the motor kicks in. I also noticed an inconsistency from the official user manual and the page you link–the recommended pedal cadence being 80rpm, not 60rpm. You ride a bionx regularly right? Perhaps you have an older model?

Perhaps you’re thinking that using the remote throttle requires you to to be moving at a default minimum of 3km per hour? That’s mentioned in official user manual…

I’ve never really felt the need to use the throttle when riding that bike. How frequently do you use yours? Does your thumb getting tired from holding it in a pressed position for extended periods of time? I usually just downshift when needed–I experience the high torque, low cadence grinding when starting from a dead stop in too hard a gear at a stoplight. I roll for a split second, down shift, and then I’m on my way. ZOOM.

Haha! Since I bought the Xtracycle without trying the Yuba, I don’t have an opinion on motors, but I DO have an opinion on kids sitting like sacks of potatoes! I have a Hooptie, and as such, haven’t tried to carry an adult, but I totally get how Bruno is saying that as passengers, cyclists will respond with their bodies in the way they would if they were doing the pedaling. On the bike, my kids act like they’re at home, which is to say, they bicker and squirm and harass each other and I am constantly shrieking “NO FIGHTING!” “KEEP YOUR BODY TO YOURSELF!” “WHO IS WIGGLING? PLEASE DON’T MAKE US FALL OVER!”

This is us on our new bike! Your input here helped me feel confident in my decision, and I really appreciate it. Our Xtracycle has genuinely changed our lives for the better. Love!

All I’m sayin’ is that three kids, at least one of whom was standing up at some points, had greater spudity than WABA’s executive director.
