The Top Fuel 5 Gen 4 is a nimble alloy trail bike that's ready to hammer up climbs and hold its own on descents - all without breaking the bank. It offers 130 mm of front and 120 mm of rear suspension that gives you just enough squish to soak up chatter without draining your power on all-day pedal fests. It comes equipped with a RockShox suspension package and Shimano Deore group set that gives you everything you need to rip in an economical package.
You want to dive into a full suspension rig and want a light, yet capable alloy ride to get you there. Cost is an important factor, and you don't mind upgrading some parts over time. You want to ride a variety of trails, from smooth cross-country to more rugged all-mountain and you need a versatile bike that stays efficient on long climbs without sacrificing confidence on descents.
An Alpha Platinum Aluminium frame with a 4-way Mino Link for adjusting geometry and leverage rate. A 130 mm RockShox Recon Silver RL fork with SoloAir spring, Motion Control damper and lockout, plus 120 mm of rear travel with an X-Fusion Pro 2 shock with a 2-position damper. It's topped off with a Shimano Deore 12-speed group set, hydraulic disc brakes, a TranzX dropper post and Tubeless Ready Bontrager Line TLR 30 wheels.
The Top Fuel 5 Gen 4 is a versatile trail bike that finds the balance between efficiency, capability and budget. Its lightweight alloy frame packs in tons of adjustment, thanks to the 4-way Mino Link, with plenty of internal storage for stashing essentials on the ride. An economical component package is ready to hit the trail now and gives you room for upgrades later.
- Its lightweight frame and versatile geometry make it the perfect choice for all kinds of rides and all kinds of riders
- The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride

Make the Top Fuel yours
Opt for light parts and a 120 mm fork for a featherweight Top Fuel, or a 140 mm fork and longer-stroke 130 mm rear shock for extra versatility. Room for a longer dropper and MX wheels lets you customise the Top Fuel into an ultimate playful trail whip.
4-way Mino Link
Easily adjust the suspension and geometry four different ways for where and how you ride. At the flip of a coin, you can ride with more or less progressive suspension and tweak your geometry for a slacker head tube and lower BB, or steeper head tube and higher BB.
New internal storage with new BITS bags
New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

The UK’s Cycle To Work Scheme has been in place for over 20 years now, offering fantastic discounts to tens of thousands of riders.
The Cycle To Work Scheme, is offered through many thousands of employers in the UK and applies to bikes of all types, whether it’s road, MTB or hybrid, and that includes e-bikes too.
Introduced in 1999, the scheme aims to encourage employees to commute on their bike for environmental, traffic congestion and health reasons. It also enables companies to demonstrate that they’re looking after the wellbeing of their people.
Obviously, you’re supposed to use the bike for commuting – and we are massive supporters of getting to work this way – but it’s fine to buy a bike that’s built for the trails. Your employer owns the bike until you pay the final ownership fee, which is based on the “fair market value” of it at the end of that period.
As well as your new bike, you can use the scheme to buy accessories, such as helmets and bags, though these have to be ostensibly for your commute. So, no full face masks, for example. If you don’t have a lock, we strongly advise that you get one along with your bike as you’re liable for the Cycle To Work payments, even if it gets stolen while you’re paying it off.
This is a salary sacrifice scheme for people aged 18 and over where the monthly payment for your bike is taken out before tax and National Insurance are deducted. Because your contribution is taken before tax, you pay off more per month for less. So, for a bike costing £1,200, £100 is taken from your salary every month but it only costs you £68 because the other £32 would have normally gone to the tax man, right? So, you pay 12 instalments of £68 and a final ownership fee of £300, totalling £1,116. If your salary puts you in the higher tax brackets, you actually save more but you get the gist.
Firstly, find out which scheme your employer is enrolled in and therefore where you can buy your bike from. We work with a number of Cycle To Work providers, including cyclescheme.co.uk, cycleplus and Bikes for the NHS.
Then you need to speak to your HR department and request a certificate, bring it to us and we’ll redeem it against the cost of your bike and accessories. The salary sacrifice commences from your next pay packet.
To get a bike on the scheme, your employer needs to sign up to a provider. If they’re unsure about how to do this, send them to us and we’ll help.
If you can find it cheaper - let us know!
As well as offering a fantastic range of cycling equipment, Big Bear Bikes is equally committed to offering great value.
