  • When an XXL frame is too small, you need a custom DirtySixer bike.
  • The brand is a specialist bike builder, providing solutions for very tall riders.
  • And now, DirtySixer has some huge pedals to go with their enormous bikes.

Cycling isn't always the kindest activity if you are a larger rider. Most bikes and accessories fit a pretty narrow spectrum of riders – being of average height and build.

For those 2m and taller riders, even the largest frame sizes feel too small. Not to mention the compromise of straining a tall body and limbs to operate within traditional bicycle geometry.

When you need an XXXXXL frame 

DirtySixer is an American custom bike brand that makes massive bikes. How big? Well, the sizing goes up to 5XL, for riders between 2.16- to 2.28m. Basketball players? They love DirtySixer bikes.

Shaquille O'Neal and Curtis Johnson are both delighted DirtySixer customers. The bikes aren't only much bigger than even the largest standard frames, but they roll 36-inch wheels too – instead of 29ers.

Experienced cyclists know that touchpoints are a crucial comfort issue when riding. You can have a great bike, but you'll suffer if the pedals or grips are incorrect.

Big bike - big pedals 

Realising that their very tall customers require custom components, DitySixer has created oversized flat pedals.

A great pedal not only prevents ankle and knee tension, but also increases confidence. Riding coaches often repeat the wisdom that bicycles are turned with the pedals and hips, not the handlebars. It is no use having a frame that fits perfectly, if you are riding on uncomfortably sized or shaped pedals.

For riders who wear enormous custom shoes, DirtySixer creates platform pedals 160mm long and 122mm wide. An average flat pedal is about 105mm long and 105mm across.

At 650g, these DitySixer pedals aren't light, but they provide all the pedalling comfort and confidence that very tall riders require. With 16 traction pins on each side, there's little to no chance of slipping one of these huge pedals, even when riding in the rain.
