DirtySixer has unveiled the MonsterEnduro, a full-suspension enduro bike built around 32in wheels and designed specifically for tall riders – but it's not a looker, with kinked top and down tubes that are sure to divide opinion.
While we’ve seen the 32in trend picking up steam this past year, with Maxxis releasing tyres and BMC testing a prototype Fourstroke, DirtySixer has championed the wheel size since 2013.
The current trend seems centred on XC bikes, with the MonsterEnduro being one of the first production enduro models to feature 140mm of rear-suspension travel.
The new mountain bike takes inspiration from the brand's 36in DH prototype shown at Eurobike and raced at Megavalanche last year.
The new bike comes in five sizes, with the smallest a size L, which is said to fit riders who are over 170cm, and the largest 4XL.
The MonsterEnduro is available at one build level, priced at $8,999, or around €7,708, plus shipping, as well as in rolling chassis form, complete with headset, fork and wheelset for $3,599.
You can also buy only the frame for $1,299.

Long-travel 32in
The frame is handmade from 6061 aluminium, using hydroformed tubing, and is designed around a four-bar Horst-link suspension layout with an expected 140mm of suspension travel.
While the travel figure may seem small for a conventional enduro bike, it's one of the longest-travel 32in-wheel bikes on the market.
The brand says: "Conventional travel categories don't really apply to bigger wheels, as they don't need that much travel to overcome bigger bumps."
Up front, DirtySixer is running a modified Manitou Dorado fork, complete with custom CNC-machined crowns, with the rear shock yet to be confirmed.
The brand hasn’t listed any finalised geometry figures, but says it is targeting a 65-degree head angle, 75-degree seat tube angle and 490mm chainstays.
As with DirtySixer's other bikes, chainstay length and crank length will increase with frame size to maintain rider proportions.
The bike uses a T47 bottom bracket with inboard bearings, paired with a narrow 186mm Q-factor, despite the use of fat-bike derived standards.
A SRAM Eagle 90 drivetrain is used for shifting, while braking comes courtesy of Magura’s new four-piston Louise brakes with 200mm rotors front and rear.
The frame uses a 34.9mm seatpost and accepts dropper posts exceeding 200mm of travel.
DirtySixer has been testing several carbon rims, but says it might ultimately use its own wheels that it developed for ebikes.
