Pedaling with Prosthetics: Maglock Pedals Offer Solution for Amputees

When we first reported on the next-generation Maglock Pedals, Dave told us that he was working on a special project. As those type of things usually go he didn’t want to divulge any details just yet but told us that the pedal showed a lot of promise for those with lower leg amputations. As you might imagine, situations where the rider has limited use of their lower leg could make using a traditional clipless pedal quite difficult.

Of course, the Maglock pedal is still being marketed as a solution for those looking for an alternative to the standard clipless pedal – but the use for amputees is exciting news if you happen to fall into that category. There are still a few days left in the Maglock Kickstarter campaign, but if you want to see what the pedal could mean to someone with an amputation, you’re going to want to check out the video after the break…

With five days left In their campaign, Maglock has far surpassed their goal, and should be delivering completed sets by September/ October. You can still pick up a set for $120.

I don’t know too much about amputees, but wouldn’t it make sense to leave that shoe away and attach the cleat directly to the prosthetic?

Cool. The vid would be more inspiring without the funeral music, though 🙂

@nsp234 I would think (not that I would know) that an amputee would want to have as much common “feel” across different movements as possible. Whether it’s walking, running, biking or otherwise.

As an amputee I can confirm your answer as spot on. It’s all about balanced feel, in body, engagement, and sight. When I look, engage and feel in balance it all comes together nicely on the bike. These pedals are exactly what we’ve been waiting for. Great work Magped, thanks!

nsp234,
I’m no amputee so I may be wrong here, but sans dedicated athlete, I guess most amputees only have one or maybe two prosthetics. Since they are used for everything, they will have a common “foot”. Requiring direct cleat mounting would require one to run a specific prosthetic.

This also doesn’t account for the fact that like regular people, amputees probably enjoy getting off their bikes during a ride (or like me, have to get off in certain sections). Using a regular “foot” with shoe allows for this in a way a direct mount couldn’t. Imagine hike-a-biking on only a metal “cleat”

I once sold a guy a pair of the precursor to these (can’t remember the brand off hand, but it’s been done before). They weighed a metric tonne, but the bearing was smooth and the platform solid. This guy was a triathlete who’d busted up his foot, but wanted to stay on the bike while it healed to keep the km’s up for an upcoming event.

We talked about ideas for a while in the shop, his physio had approved ccycling, provided he limit the ankle movement – so he really needed to be attached to the pedal at the heel basically. So conventional clipless just wasn’t going to happen. We came up with using the ancient magnetic’s the shop had laying around and a crappy old sneaker.

He went away with a barely formed plan, and came back a few weeks later in full kit having just ridden 200km on the highway and showed me his shoe.

TLDR; While this is obviously not an ideal direct replacement for conventional clipless systems, it’s really great to see a different take – done well – that offers different advantages for people with different needs or uses

Hey Graham, reddit much?

I’m a below knee amputee and this is a cool idea since clip less pedals don’t work well for us. It’s difficult to twist out and even if you loosen the clip up now it doesn’t hold the foot well. The magnet needs to super strong to keep the foot from sliding off under rough trails. I use Power Grip straps to hold my foot on and they are pretty easy to get out of with practice.

And yes, a cleat is attachable to the foot but not the greatest idea for switching between riding and walking.

Wow…I am an amputee and I race BMX. I also ride a park bike at skate parks as well as ride a mountain bike for cross training. I race with clip pleas pedals, but use flat pedals for training on the race bike. I use a toe clip on the prostitic side to keep my shoe/foot in place. These pedals offer a great opportunity to amputees looking for a casual ride, but how well will they handle the rigors of BMX, park and MTB riding. Looks like a great product.

I am an amputee… And clipless pedals have been a challenge.
I tried 4-5 different pedal systems with varying degrees of success.
I can see the magnet system being great for a quick step down instant alignment and engagement type of setup. Not sure they would hold me in place on rough trails or when needing to bunny hop. But for some amputees I could see this working well. I personaly use crankbros Eggbeater pedals they can take practice getting your prosthesis into the right spot but engagement is super easy and secure with plenty of float. It is the only system I will use anymore.

As for clipping the prosthetic directly it would require the prosthetic to be slightly longer to accommodate the lack of shoe and would be awkward in hike a bike sections or off bike walking. Similar to trying to walk in slippery road shoes with time cleats…no fun.

Thank you to the amputees that chimed in here. A question for you (or for a kinematics expert): It seems like eliminating the foot at the bottom of a prosthesis would change the hip/thigh/knee pedal dynamics. Can anyone comment as to if that is a positive or negative thing, or if it varies from individual to individual?

notamachinist-
Yeah, you’re right, but if the individual has a short lower limb then they can’t always deal with the fore-aft leverage a “normal” cleat placement provides. My friend, for this reason, rides with the cleat just about 1″ forward of the prosthetic’s plumb line axis and uses a shorter crankarm on the prosthetic side to compensate. Going to a shorter crank really helped her keep the hips stable. She also uses a specialized bike “leg”, but would also qualify as a dedicated athlete.

Hmmmm, yeah? maybe? ok, heres the deal…..From what I saw on the video he isn’t doing anything extreme where it requires a lot of torque being put on the pedal up or down. obviously the magnet cannot be strong enough so that you can still be able to unclip easily, I have already tried something similar to this by using a very low tension clips from Shimano, but only on the road and it worked. However, whenever I would start throwing down some wattage and even hitting a pothole here and here I would come upclipped, which is something you do not want!! Specially if you are on a climb standing up pulling hard on the pedals or descending. You can still unclip out of normal clip in pedals, you just have to use serious torque from your hip, it doesn’t always work but I must rather do that versus come out of the pedals on a bumpy descend or whatnot. Now, for someone who is doing a sport such as BMX? Yes, it would be very beneficial to them as well as just for recreational riding. As for me? I would be terrified to use one with the way I ride and type of riding I do.
