AnswerBMX MPH Junior Platform Pedals in Blue

The blue MPH Junior at a glance

This is AnswerBMX’s junior-size race flat in blue, part number PD-APD15JFLT-BL. Underneath the color it is identical to the black version: a pinned aluminum platform on a chromoly 9/16” spindle with sealed cartridge bearings and 13 removable pins per side.

So the choice between them is purely about looks. For the thread check and installation steps, see the black MPH Junior page; this page covers color, fit and the brand.

Matching blue pedals to a build

Blue pedals work best when they repeat a color already on the bike. A few tips for color-matching a BMX race build:

• Pick one or two accent parts to match, such as the stem clamp, seat clamp, hubs or grips. Blue on every part tends to look busy on a small bike.
• Expect shade differences. Blue finishes vary between brands and even between production batches, so a pedal and a stem from different makers rarely match exactly. Matching to a black-and-blue scheme is more forgiving than chasing an exact tone.
• Think about wear. Pedals take the hardest hits on a bike: crashes, gate starts and track edges. A colored finish shows bare aluminum where it scrapes, while black keeps a cleaner look for longer.
• Buy pins by model, not color: see pedal pins.

If you want an exact match across many parts, choose them from the same brand where possible: AnswerBMX makes other BMX race components, and Answer BMX lists them.

Sizing and fit for kids and juniors

The MPH Junior is the smaller of AnswerBMX’s two MPH flats, made for smaller riders. Its platform is compact (around 100 mm in each direction on retailer listings), which suits a small shoe much better than an adult pedal.

How to tell whether it fits your rider:

1. Shoe coverage. Stand the rider on the pedal with the ball of the foot over the spindle. The sole should cover most of the platform, with no more than a little overhang at the front and back.
2. Pin contact. With the foot in place, the outer pins should sit under the edges of the sole. If the shoe is narrower than the pin pattern, the outer pins aren’t doing anything.
3. Room to adjust. Kids move their feet a lot. If the rider is struggling to reposition, remove a couple of inner pins until their technique improves.
4. Time to move up. When the shoe clearly overhangs front and back, move to the MPH Senior or a mid-size adult flat.

Pair the pedals with flat-soled shoes. Skate-style shoes with a soft, flat sole grip pins far better than running shoes with deep lugs. Shin pads are a sensible extra with pinned pedals.

Check the crank before you buy

The blue MPH Junior is listed with a 9/16” spindle only. Bikes with three-piece cranks, including many junior BMX race bikes, take 9/16” pedals. Many budget kids’ bikes use a one-piece steel crank that needs 1/2” pedals instead, and the MPH Junior won’t fit those. The left pedal is reverse-threaded on both types: see which pedal is reverse threaded.

About AnswerBMX

Answer traces its history to 1976, and AnswerBMX is the brand’s BMX racing line. In recent years it has concentrated on race hard parts, with flat pedals like the MPH Junior and Senior and clip pedals like the Power Booster Jr, and the company says its parts have been raced by Olympic, World and National champions.

For a junior racer, that race focus shows in the design choices: a low, compact platform, plenty of replaceable pins and sealed bearings, rather than the resin pedals that come on many complete kids’ bikes. For more junior and BMX options, see our platform pedals guide.
