Rocket: full power e-MTB that rides like a Cotic
That matters more than it sounds. Most e-bikes, however capable or powerful, feel different from a regular mountain bike in ways that are hard to ignore. Heavier. More planted. Less willing to change direction when you ask. The Rocket doesn't feel like that. It feels like you on a great day - stronger, fresher, and more capable – without surrendering the natural rhythm and responsiveness that makes mountain biking worth doing in the first place.
One independent reviewer called it "the best bike I've ever ridden, full stop. E or otherwise." We'd humbly suggest that's the whole point.
A slim T45 down tube, rather than a drainpipe-sized chunk of metal or carbon, means the Rocket retains genuine chassis flex and feedback. Going back to other e-bikes from the Rocket, riders and reviewers consistently describe them as feeling "dead" by comparison. That life, that Cotic feel, is what the steel frame preserves, even with a motor in the mix.
Why The Rocket?
You love riding but want to do more of it. More laps, more climbing, bigger days.
You've looked at e-bikes but been put off by ones that feel heavy and unresponsive.
You've lived with built-in battery bikes and know what a pain they can be.
You're a Cotic rider and you're not willing to give up that feel just because you want a motor.
You want the confidence to tackle trails you might have thought twice about before.
You want a bike that will still feel special in five years, not just five rides.
You want it built properly, with after-sales support from a brand that answers the phone.
Front triangle, seatstays, swingarm, CNC parts, 3D printed parts... all UK made, and then assembled right here at our HQ on the edge of the Peak District.
Radical Longshot geometry keeps the bike stable through the rough stuff, planted in the corners and pinpoint accurate in the steep tech.

| Frame size | Rider Height in centimetres | Rider Height in feet and inches |
|---|---|---|
| C5 | 184cm - 195cm | 6ft 0in - 6ft 5in |
| C4 | 182cm - 190cm | 5ft 11in - 6ft 3in |
| C3 | 176cm - 184cm | 5ft 9in - 6ft 0in |

| C1 | 162cm - 172cm | 5ft 4in - 5ft 8in |
The chart is a guide to frame size. Longshot Geometry means that the frames are low and long, with plenty of standover room. We recommend going for the size suggested for your height on the chart, and getting all the benefits of running a super short and responsive 35-40mm stem. It's a game changer.
If you are unsure about that or anything else, drop us a line at size@cotic.co.uk and we'll be happy to discuss set up based on what you're riding at the moment and what seatpost you are planning to use.

Bike Specs & Prices
Complete bikes from: £7599
Bikes are now available worldwide, with free shipping to UK, Ireland and mainland Europe.
We have several levels of stock build which are based around our favourite parts in builds you can trust. We never specify anything we haven't ridden, tested and enjoyed. However, just about everything in your build can be customised to help with fit (contact us if you need help) or to personalise your bike. Want a different fork? Shock? Brakes? Wheels? Tyres? Bars? Stem? Longer drop seatpost? Women's saddle? Men's saddle? Colour matched Hope components? No problem. It's your bike.
All the bikes are assembled from a frame right here in the UK by us. We can do everything from bare frame to complete bike: Send us your favourite saddle and grips to fit. Send us your wheels if you have a nice pair you want to use. There's no point you getting kit you don't want. It's wasteful. That gives you almost limitless options to customise and tune your bike to your needs. If you can't see an option you'd like on the order form, get in touch. We all know it's good to head off piste sometimes!
Tap on a build title below to see the default specification and price for that build... then hit the 'CONFIGURE YOUR BIKE' button to see all the customisations you can make to the build. When you select your country at the bottom of the form, sales taxes (VAT), pricing and shipping will automatically update for you. Once you're happy, order your bike!

Origin : MADE IN UK
Cotic frames are designed, developed, engineered and tested entirely by us at our base in the Peak District, near Sheffield 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. They are fully certified and lab tested in excess of the requirements of ISO4210 safety standards.
For the ebike 100% of the frame is made and sourced in the UK. The skilled guys at Five Land Bikes in Scotland manufacture the Reynolds 853/T45 front triangles and seatstays in small batches, to their exacting standards. Coal Industries fabricate the bespoke Cotic aluminium swingarm using parts CNC'd by Rideworks. Almost every single frame part, components, nut and bolt is sourced and produced in the UK for the ebike.
All the major steel parts of the frame are dip coated in manganese phosphate to prevent corrosion, before being painted using tough and durable automotive spec paint. 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.
