Key Quotes
Alice thinks the Fuel EX Jr is a great bike and it has definitely improved her riding and boosted her confidence.
MBR logoMBR
It’s only available in size small (15in), and depending on rider height, it should fit kids aged between eight and 12 years old.
MBR logoMBR
£1,400 is a huge amount when you may only get six months’ use, although you may claw quite a bit of that back on resale.

Trek Fuel EX 5 Women’s 27.5 Plus

Nov 2017

While this Trek Fuel EX 5 may look like a roller skate on wheels, complete with disco-tastic 'anthracite' metallic grey finish and chunky platform shoes reminiscent of the Spice Girls’ heyday, it does cover a particular niche between ‘trail’ and ‘cross-country’, and it does it very well on a respectable budget.

2017 Trek Fuel EX 9.8 // Bike Review

Nov 2017 · Will Hilbert

Take a look at the new Fuel EX and you will quickly see Trek has fully redefined the model. The 2016 Fuel Ex 29 was a step in the right direction, but it was a timid half-hearted step that left the rider wondering what if…? What if it came spec’d with a stiffer fork, more travel and a slacker headtube? The team at Trek delivered and the 2017 bike answers these questions. It now allows the use of 29” or 27.5+ wheels and is one of the stiffest frames in the category, featuring a totally new geometry that’s slacker and longer than its predecessor.

One Ride Review: Trek Fuel EX full suspension trail mountain bike

Nov 2016 · Tyler Benedict

Earlier this year, the Fuel EX received rapid fire updates that first introduced a 27.5+ version then quickly made it the standard model by adding 29er wheels and tires for most of the stock builds. The frame was all new for both, bumping travel to 130mm, and it effectively did away with the standard 27.5 …

[First Look] Riding the Trek Remedy 9.9 & Fuel EX 9.9 in Squamish

Jun 2016 · Ian Collins

[ad3] Just about one month ago we had an opportunity to spend 2 days shredding with Trek up in Squamish British Columbia aboard both the new Remedy 9.9 Race Shop Limited and the new Fuel EX 9.9.  We spent a full day aboard each bike in varying conditions ranging from fun, flowy and jumpy trails to undulating singletrack with techy climbs and offbeat descents.  We saw a mix of rocks, roots, loam and groomed trails.  In a short couple of days we got quite a bit of saddle time, and a large portion of it was spent in rainy conditions; something we
