Summary

The BMC Fourstroke is a lightweight and fast cross-country bike designed primarily for racing, featuring progressive suspension and modern geometry that enhances handling and speed. It excels in flat-out sprints and descents but can feel harsh on rugged climbs and comes with a high price tag. The integrated dropper post is a notable highlight for added control, though some components may not suit all conditions.

Pros
  • Lightweight and fast design

  • Progressive suspension for efficient performance

  • Modern geometry improving handling and stability

  • Integrated dropper post for enhanced control

  • Stiff frame providing direct feedback

Cons
  • High price tag

  • Harsh ride on rugged terrain

  • Limited dropper post range for some riders

  • Tires may lack grip in wet conditions

  • Travel may be insufficient for chunkier trails

If you’re concerned with winning, this is the bike for you. If you’re concerned with value, it is not.

Who doesn’t like riding fast? The Fourstroke offers exceptional speed in every situation backed up with the soothing stability and control from geometry that is a world away from old fashioned XC bikes, plus the integrated dropper is a real highlight and a benefit on rowdy terrain when you’re riding on the limit.

BMC Fourstroke 01 LT One first ride review - MBR

Jul 2022 · Alan Muldoon

Tom Pidcock’s race machine with a bit more oomph, BMC’s Fourstroke LT gives mere mortals a bit of a safety net that takes it into best down-country territory. Need to know Long-travel version of the BMC Fourstroke that Tom Pidcock races Fox 34 SC fork delivers 120mm travel to match the rear Remote lever offers three distinct suspension modes Integrated bump-stops protect the frame and allow for straighter and stiffer downtube Sag indicator on the upper link makes for easy suspension set up Available in four frame sizes Priced at €8,499 (no UK pricing as yet) Tom Pidcock is one lucky son of a gun. And not because Mathieu van der Poel went out the front door at the 2020 Tokyo Olympics. It’s not even because on any given day he can race for the win at the highest level in road racing, cyclo-cross or mountain biking. That’s down to a lifetime dedicated to his craft and good genetics, not good fortune. When I say Pidcock is lucky, it’s because he was in the fortunate position of being able to choose which mountain bike he wanted to race. A rare position for a sponsored rider at any level, let alone someone capable of competing for, and ultimately winning, Olympic gold. How did he find himself in this particular situation? He currently rides for Ineos Grenadiers and the team is sponsored by Pinarello for Road and Cross. Because the  Italian brand doesn’t make a XC full-suspension race bike, that left Pidcock free to choose. Rumour has it, he tested a bunch of bikes from different brands before settling on the BMC Fourstoke. Not that you could tell he is riding one as all of the graphics have been removed. Now, given that BMC gets no direct publicity we can only assume that no money changed hands and it was genuinely Pidcock’s first choice. That, or, it is one of the best guerrilla marketing campaigns ever. Given that Pidcock has a custom build with electronic SR Suntour suspension, it’s hard to know which configuration of Fourstroke he’s riding. That’s right; there are two, and both use the exact same full carbon frame. The standard Fourstroke gets a 50mm stroke shock to deliver 100mm of travel, while the LT version we have here retains the same eye-to-eye length but gets a 5mm longer stroke to boost travel to 120mm. But the numbers don’t quite add up. If the standard Fourstroke delivers 100mm of travel from a 50mm stroke shock that gives it a 2:1 leverage ratio. Now, given that BMC upped the shock stroke by 5mm on the LT, it should be obvious that it will only provide an extra 10mm of travel. So the LT is a 110mm bike not a 120mm bike, which is exactly the amount of travel that I measured in the workshop. To confuse matters further, the stock Fourstroke actually has 104mm of travel, and BMC rounds it down. The shortfall in travel on the LT could also …Continue reading »

Highs
  • Progressive geometry with a fast efficient ride feel. LT version is only 0.5kg heavier than the race version.

Lows
  • Could be plusher in the open suspension setting. Restricted to one dropper post option.

BMC Fourstroke 01 LT ONE – In our big 2022 downcountry group test

Mar 2022 · Simon Kohler

At first glance, it’s hard to tell apart the BMC Fourstroke 01 LT ONE from its XC counterpart. However, the beefier fork, aggressive tires and extra travel promise better trail performance. But is it just mere promises or can the BMC deliver on the trail?

Highs
  • Good balance in the attack position

  • Intuitive handling

  • Very efficient when pedaling even in fully open mode

Lows
  • Restricted freedom of movement

  • Rear suspension lacks sensitivity downhill

  • Brakes don’t do justice to the character and intended use of the bike

BMC Fourstroke 01 Two AXS review

Mar 2022 · Tom Marvin

It might have an Olympic Gold, but does it deserve a medal on our trails?

Highs
  • Solid suspension

  • Decent geometry is comfortable up, and confident down hill

Lows
  • Stock tyres are poor

  • The dropper is neat, but ultimately not as good as a ‘proper’ one

  • Climbing Performance

  • Pure Speed

  • High-Gloss Paint

  • Great Spec

Lows
  • Dropper post limited range

  • Uncomfortable in the air

  • Not as comfortable descending as similar bikes
