Jeht: The Corner Wizard

You know that feeling when you hook up a perfect turn and the whole bike just tracks? The Jeht is built for that. It's a dedicated mixed-wheel (mullet), made in Britain trail bike with 150mm rear travel and a 150-160mm fork, designed to carve through corners and feel the edge knobs bite.

Evolved Cotic Longshot geometry puts you in a "stand tall" position in the middle of the bike, with a planted front end that lets you commit. Reynolds 853 steel front end adds the supple, connected ride feel that decades of Cotic development have tuned.

New Cotic Rocklink takes everything we learned from our proven droplink design and makes room: a fully open front triangle and full dropper insertion, with the same supple, supportive, lively ride.

This isn't a monstertruck that numbs the trail. It's a rally car that dances and jinks, finding grip instead of grabbing brakes.

Why Steel?

Steel on a full-suspension bike isn't nostalgia. The Jeht's front triangle is Reynolds 853, with Cotic exclusive Ovalform top tube and dedicated down tube, a proprietary heat-treated steel strong enough to build light, with the compliance to give and go as the trail pushes back. Out back, a T45 steel seatstay and a 6082-T6 aluminium swingarm bring authority where you need it, and masses of tyre clearance.

The Cotic Jeht Gold build tops out the range with Shimano XT Di2 wireless shifting, a Rockshox Lyrik Ultimate fork and Super Deluxe Ultimate shock, Reserve aluminium wheels on DT350 hubs, and Hope Tech4 GR4 brakes, the full enduro package.

Features

Origin

MADE IN BRITAIN

Cotic frames are designed, developed, engineered and tested entirely by us at our base in Chesterfield, on the edge of the Peak District in the UK. Our founder - Cy Turner - is the lead designer and engineer, and our frames are rigorously ride tested by everyone at Cotic and chosen test riders and ambassadors. The Jeht is fully certified and lab tested in excess of the requirements of ISO4210 MTB safety standards.

The Jeht frame is 100% UK made. The skilled guys at Five Land Bikes in Scotland manufacture the custom Cotic designed Reynolds 853 front triangle and T45 seatstays in small batches, to their exacting standards. The aluminium swingarm and CNC machined parts come from hand picked UK makers.

The frames are ED Coated to prevent corrosion, before being painted using tough and durable automotive spec paint by the Five Land guys. After they have completed their painstaking hand finishing process and their rigorous QC, the frame parts undergo further checking by us before assembly in the workshop at our HQ.

Frequently asked questions

What is the Cotic Jeht?
The Cotic Jeht is a steel full suspension trail and enduro bike, mixed-wheel (mullet) with 150mm of Rocklink rear travel and a 150-160mm fork. It's built around evolved Cotic Longshot geometry for fast, confident cornering.
Where is the Cotic Jeht made?
100% of the Jeht frame is made and sourced in the UK. Five Land Bikes in Scotland manufacture the Reynolds 853 front triangle and T45 seatstays, and the aluminium swingarm and CNC machined parts come from hand picked UK makers. Complete bikes are assembled to order at Cotic's Peak District HQ.
Is the Jeht officially certified as British made?
Yes. The Jeht carries the official Made in Britain trademark, a registered mark licensed only to verified UK manufacturers.
How much does the Cotic Jeht cost?
Framesets (frame and shock) start from £2,999. Complete bikes start from £4,849.
What sizes does the Jeht come in?
Five sizes, C1 to C5, suiting riders from roughly 5ft 3in to 6ft 5in.
What frame material is the Jeht made from?
A Reynolds 853 steel front triangle with Cotic's exclusive Ovalform top tube and HD seat tube, T45 steel seatstays, and a 6082-T6 aluminium swingarm.
What is Rocklink suspension?
Rocklink is Cotic's current full-suspension linkage, developed from their proven droplink design. It delivers 150mm of calm, controlled rear travel with a supportive, progressive feel, while opening up the front triangle for a bottle, tools, and full dropper post insertion.
What's new on the Jeht?
The current Jeht (Gen3) introduces the new Rocklink suspension design in place of the previous droplink layout, a fully open front triangle with room for a bottle and tools, full dropper post insertion, UDH compatibility, and evolved Longshot geometry.
What wheel size does the Jeht use?
A mixed-wheel (mullet) setup: a 29" front wheel and a 27.5" rear wheel, up to 2.6" wide.
Can the Jeht run a coil shock?
Yes. The frame's 185x55 trunnion mount shock fitting is compatible with both air and coil shocks.
What's the difference between the Trail and Enduro Jeht builds?
Both share the same frame and Rocklink suspension. Trail builds run a 150mm fork for a quicker, more playful feel; Enduro builds step up to a 160mm fork for more capability on steeper, rougher terrain.
Does the Jeht fit a dropper post?
Yes. It uses internal dropper routing via a down tube port, with maximum seatpost insertion given in the geometry tables for each size.
What headset does the Jeht use?
A 44mm headset for taper steerer forks: Hope 2H, Cane Creek ZS44 top/EC44 bottom, or Chris King Inset I7.

Yes. A La Carte custom paint is available on the Jeht, in addition to the stock Matte Metal Grey.
