What is the Difference Between the Fort Knox and Stealth Pedals?

The Fort Knox pedals were our first design. They are heavier (2.5 lbs per pair - the pedal body is made of aluminum) and are designed for more aggressive riding (various types of mountain biking - enduro, downhill, etc.). They have the stronger attractive connection between the two pedals (40-45 lbs of magnetic attraction per pedal)

The Stealth pedals are our second design - they are lighter (2.0 lbs per pair - pedal body is made of a durable composite nylon plastic), and are great for XC biking, everyday/beginner-to-intermediate trail rides, commuting, road cycling, etc. They have about 35-40 lbs of magnetic attraction per pedal.

What type of shoes do I need for your pedals? Do you have any recommendations?

You will need to purchase shoes that have a 2-bolt system (also known as a  2-hole system). Shoes with a 2-bolt system are most commonly used with SPD pedals, crankbrothers pedals, and other brands of pedals, but we have designed our pedals and pedal cleats to be compatible with this system. Our pedals are not compatible with shoes that have a 3-bolt system.

We strongly recommend using mountain biking shoes with our pedals, whether you are mountain biking or road biking. When shopping for shoes, look for the following:

  • A 2-holed cleat system (*REQUIRED*)
  • Flat soles – our pedals are essentially flat pedals with magnets inside, so shoes with flat soles (as opposed to contoured soles) work best. Contoured soles will make connection to the pedal difficult.
  • Rubbery/soft soles – helps with gripping the pedal.
  • The cleat area is slightly recessed in the shoe – helps keep your feet closer to the pedal, giving you more points of contact on the pedal, and better grip.

Road cycling shoes that have a flatter sole and a 2-hole setup might work with our pedals, but it’s a gamble… the cleat attachments may be your only point of contact on the pedals, making your feet feel like they are "skating around" a lot on the pedal.

Can kids use MagLOCK pedals?

Yes (except for use in BMX racing for ages 12 and under). We recommend removing some of the magnets (at least at first) because the magnetic connection may be too strong for kids.

Crank Arm / Pedal Size and Threading

The standard size and threading on most bicycle crank arms is 9/16" x 20 tpi (threads per inch). Our pedals will only fit with this size (don’t stop reading here)! There is one other size – 1/2” x 20 tpi – that exists for some crank arms; however, you can still install our pedals with a crank arm/pedal adapter. I’ll describe how you can know the difference, and provide the link to the adapters further down below:

As mentioned before, the other, less-common crank arm hole size is 1/2’ x 20 tpi. Cranks that have this size are known as “Ashtabula,” or “one-piece” cranks. They are found mostly older American-made bikes, as well as many children’s bikes, such as Schwinn, Huffy, Mongoose, etc. (the ones you typically find at Target, Walmart, or other department stores).

The simplest and easiest way to determine your crank arm’s size and threading is with a good old-fashioned ruler. You will need to remove one of the pedals from the bike and measure the diameter of the hole where the pedal is inserted.

If your bike cranks happen to have the 1/2" x 20 tpi hole size, there’s a bike parts manufacturer (F&R Cycles - fnrco.com) in Paramount, California that makes a set of adapters that converts the 1/2” hole to a 9/16” hole. You can find their adapter on Amazon for $33.99 (price as of February 2021): https://www.amazon.com/Alta-Bicycle-Adapter-Cranks-Pedals/dp/B07BTDT524/

Do you have a money back guarantee?   

No, but we do offer a limited 30-day return policy. To be eligible for a return, your item must be unused (or have very few signs of use) and in the same condition that you received it. After 30 days have gone by since you received your order, unfortunately we can’t offer you a refund or exchange. It must also be in the original packaging.

Please see our full return policy here (should say we accept returns until 30 days after you receive your order, instead of “30 days after purchase”).

We also have a "demo program" that lets you try our Fort Knox pedals for 30 days before you decide to keep them or return them. We don't have a demo program for our Stealth pedals yet.

What is the Purpose of the Toe Stops?

The toe stops were designed to reduce the amount of side-to-side and forward-backward movement that occurs on the surface of the pedal. Some people get the feeling that they are "ice skating" on the surface of the pedal - the toe stops help reduce this by about 60-70%.

Will the Toe Stops Prevent Me from Getting Out of My Pedals?

No, they were designed to reduce the amount of side-to-side movement that occurs on the surface of the pedal (although the steel plates attract to the magnets inside the pedals, some people get the feeling that they are "ice skating" on the surface of the pedal, and the toe/heel stops help reduce this by about 60%. You will still be able to detach from your bike easily if you need to.

Are Your Pedals Good for Children Amputees?

Thanks for reaching out! Maglock has a good number of customers who are amputees, and as far as I've seen, they've been very helpful in staying connected, and also quickly getting out when needed (a quick knee jerk to the side will get you out). Here's a video we made of a below-the-knee amputee: https://www.youtube.com/watch?v=bCAfz9G3PTQ - You can see him unclip with his prosthetic around 1:34-1:37.

The only potential issue is threading compatibility between our pedals and your child’s bike.

Can MagLOCK pedals be considered a Qualified Medical Expense for a Flexible Spending Account (FSA)?

The following should not be taken as professional advice (we just make bike pedals, we’re not tax law experts):

The best thing to do would be to consult a tax law expert, but as far as we can tell, it’s a possibility. It looks like they could be considered “potentially eligible”. Here are a couple references we’ve found online. Passage of the CARES Act on March 27, 2020 may have changed some laws that were previously in effect:

“Exercise equipment is eligible for reimbursement with a Letter of Medical Necessity (LMN) with a flexible spending account (FSA), health savings account (HSA) or a health reimbursement arrangement (HRA). Exercise equipment is not eligible with a limited care flexible spending account (LCFSA) or a dependent care flexible spending account (DCFSA).” - https://hsastore.com/HSA-Eligibility-List/E/Exercise-Equipment-E279.aspx
“[Exercise equipment] [m]ay be eligible for reimbursement if prescribed by a physician to treat a medical condition (such as obesity or heart disease) and the purchase would not have been made if it weren’t for the medical condition.” - https://www.benefithelpsolutions.com/-/media/BHS/pdfs/members/guides/fsa-eligible-expenses.pdf


Many websites also state that “the purpose of the expense must be to treat the disease rather than to promote general health.”

You can find a Letter of Medical Necessity form on many websites, but here is one: https://mybenefitwallet.com/CMS/docs/default/LetterOfMedicalNecessity.pdf

Can MagLOCK pedals qualify as a Medicare or Medicaid expenditure?

The following should not be taken as professional advice (we just make bike pedals, we’re not tax law experts):

The best course of action would be to consult an expert on Medicaid and Medicare. But according to the CMS (Centers for Medicare and Medicaid Services), exercise equipment is not considered DME (Durable Medical Equipment), so we think probably not. The CMS defines DME as equipment that:

  • Can withstand repeated use; i.e., could normally be rented and used by successive patients;
  • Is primarily and customarily used to serve a medical purpose;
  • Generally is not useful to a person in the absence of illness or injury; and,
  • Is appropriate for use in a patient’s home.
