Nikola Pedals: Pedal Like a Skater

You've been pedaling wrong.

I know what you're thinking. You probably thought it was enough that you pedaled in circles, and maybe even "ankling" like all the bike magazines used to say you should (do they still say that?). You might have even switched to clipless pedals that allowed more "float" to protect your knees. But none of those things is enough.

A totally new pedal design that incorporates a completely different movement has recently been developed by Nikola Innovation. At first glance, they don't appear to be much different from any other Look-type clipless pedal, but the Nikola pedals utilize something the company calls "Zivo Technology" which is a fancy, copyrighted name that means that the pedals have about 25 mm of lateral motion on the spindle.

The pedals come from Cleveland, Ohio, and were developed by Nick Stevovich who has a background in speed skating. After studying the motion of speed skaters, whose leg movement takes a lateral path as the leg extends, Stevovich believed that if a cyclist could achieve a similar movement, then they would put more muscles into the pedaling motion, and they would see more power output as a result. An added benefit is supposed to be that it might offer a more natural movement which could ease knee and/or hip pain for some riders (that claim is currently being studied).

The pedals have been tested by the Human Performance Lab at Cleveland State University in a study involving 50 riders. According to Nikola, 70% of the riders showed a 2% improvement in efficiency, and 7% more peak power. And of course, they can tell you how much time that translates into for a 40km time trial (because you always have to know how many seconds new tech will save in a time trial): 135 seconds. That's supposedly more time saved than using aero bars, a skinsuit, or an aero helmet. Okay - obviously, I couldn't care less about performance claims. But if there is actually something to the biomechanical benefits of the movement that might benefit people with hip or knee problems, then that might be worth looking into.

There are currently two versions of the pedal - one made with stainless steel for $339, and a titanium version which sells for $549. The company claims the skating-motion pedals will benefit not only racers, but also commuters, and stationary bike users. Unless the prices come down, though, I don't imagine too many commuters seeking these out.

The Nikola pedals are definitely not something I've seen before. Time will tell if they're a success, but I do know that the pedals are getting a lot of attention in the cycling press and blogs. As with most new technologies, I'm a bit skeptical -- but having never tried them, it's hard to be too sure. Would the side-to-side movement feel natural -- or awkward? As it is, I've long happy enough with traditional toe-clip and strap pedals that I don't see myself plunking down big bucks to try to pedal like a skater. Any thoughts?

  1. I suspect these might feel sketchy on challenging terrain, where the feet are control surfaces and not just propulsion levers. Probably little need to bring out a mountain-bike model.

  2. $339-$549 for the pedals and another $339-$549 for shoes to fit? That's a sinful waste. People will do anything to separate you from your money. Like you, I use toe-clips and straps and no toe-clips or straps. I enjoy cycling like that. I feel movement, adjustment in that arrangement.

    1. Yeah -- the price would be a major deterrent for most people. I just a moment ago had a friend here at work comment how she'd like to try these since she often has some knee troubles, but there's no way she could justify the cost, especially when she couldn't be sure they would be helpful for her or not. At that price, you'd really want to be sure they'd help before plunking down money.

  3. There's no way the cadence in speed skating is anywhere similar to cycling, exccept when climbing a big hill in a high gear.

    1. John--That's exactly what I was thinking as I read about those pedals. I haven't done a lot of skating, but I've done enough to say that while it's good for cross-training, it's not the same as cycling, any more than swimming, running or skiing are. When we pedal, our feet move in circular motions, while skaters propel themselves with lateral thrusts.

    2. I do have to wonder how much that 1" of lateral movement could help. Yeah - speed skaters have that "back and outward" movement -- but isn't that just a function of how skates work? Does it necessarily translate into propelling a bike? I don't encounter problems with knees and hips while cycling -- but I can imagine that there might be some people who could find some relief in that bit of lateral play -- but that's a lot of money to plunk down without knowing.

  4. It is an interesting theory. However, one also has to think about how this affects the cornering angle. Sometimes you just need to pedal through corners (particularly while racing). A 1" lateral float might make this impossible, which in practice could negate any claimed performance gains.

    1. Given that this is mainly being aimed at racers so far, that could be a very legitimate issue.
