"Pedal steer" and Cruzbike recumbent road bikes: this might surprise you
We recently dropped a new video. Check it out below if you haven't yet. We had a blast shooting it. You'll see lots of new faces riding - all of whom learned to ride a Cruzbike in one day for this video.
It's not unusual for someone in the comments to be curious about "pedal steer" when we promote our platform's superiority. This probably comes up because they have heard from others in non-Cruzbike recumbent road bike or trike circles that this is a negative to our patented drive system:
@Recumbone writes, "I'm not seeing the pedal steer that happens whenever you ride a Cruzbike. It does happen. Why not show it?"
For starters, experienced Cruzbikers will definitely recognize quite a bit of pedal steer among these awesome Cruzbike newbies at our shoot in Florida. With the exception of Jim and Maria, everyone in this video was brand new to the platform.
Either way, we figured this would be a great time to dig into the "pedal steer" phenomenon. So let's go:
The surprising truth is that pedal steer is actually the secret sauce that makes Cruzbike the most ridiculously fast and fun road bike in the world.
Here's how Cruzbike co-founder Jim Parker describes pedal steer:
"To beginners, pedal steer is the scary realization that you have the ability to steer the bike by applying pressure to the pedals with your feet.
The reason it's scary to beginners is that they are untrained and uncoordinated in their pedaling dynamics.
Everyone wobbles at least a little bit on those first Cruzbike rides due to pedal steer.
Experienced Cruzbikers have cleaned up their pedaling dynamics (this happens naturally with time) and coordinated their core muscles and upper body to sprint past other riders, or climb fast up hills.
Pedal steer allows us to get more torque, more power, through the cranks into the propulsion of the bike.
So embrace "pedal steer", don't fear it.
The official term for our patented drive system is "Dynamic Boom Front Wheel Drive." Pedal steer is an essential component of this drive system, along with stiffness, lightness, and mechanical efficiency.
And for those who really enjoy riding no hands, and put in the required hours of practice, pedal steer allows Cruzbikes to be steered more precisely 'no hands' than any other bike."
@Billy Kessler I love a good vector analysis. Thank you! Looking at your diagram, I might suggest the driving pedal force is directional from the hip, rather than from the center-line of the bike, but I doubt that will have much impact on your conclusion, which is that any pedal steer forces are pretty easy to counteract with your upper body.
A vector analysis explaining why pedal steer is small (on my Q45 the steering effect is about 10% of the total pedal force) is on the CB forum (link below). See the vector diagram at the bottom of the post.
