IMPORTANT NOTICE: Please be advised that the workshop is now temporarily closed, due to Grim himself having had a MASSIVE accident at Bike Park Wales (October 2025). This has left him recovering from spinal surgery which will be a long road… unlike the berm that he went off. Send good vibes đ€
A small, home-based, family business
Grim’s bikes is a small workshop in the Surrey Hills that helps local bikers get the best service for their mountain bikes and road bikes. No bullshit; we treat every bike as if it was our own, and we try and have a fun time helping people.
The workshop is run from Grim’s home, so you do need to book in a time slot if you want your bike repaired or serviced.

About Graham
Written by his very lovely, very patient wife.
I was going to subtitle this âHis love affair with two wheelsâ, however it actually started on three, as a toddler, with him crashing into a garage door on his tricycle. He hadnât really appreciated the speed with which heâd be going by the time he arrived at the bottom of a very steep slope, resulting in broken bone number one⊠not much has changed since.
Throughout his youth, two wheels remained a constant, and home-built bicycles were replaced with bikes with engines⊠motorbikes became his thing, he still gets misty eyed for the Kawasaki GPZ900R that he owned when I first met him at college in 1986. Recently rushing to hit pause on the film Top Gun Maverick when Tomâs original GPZ900R, was revealed. Proving once and for all, that Maverick and Graham are surely almost exactly the same person⊠or at least have the same taste in bikes.
He then switched to a Yamaha Super Ténéré to circumnavigate the world⊠twice. (I shit you not.) Some might say it was an act of heroism, others might say he was putting off getting a job. Whatever, it was a helluva ride!

Before the trip, he attained a City & Guilds qualification in Motor Mechanics in the hope of snagging some paid work en route, and famously ended up as the RAC man in the mining town Kalgoorlie, Australia* for a few months while getting his bike back on the road.
[* – Well, youâd know this if you have ever joined us for Sunday lunch. Our world-class roast potatoes are always served up with a healthy dose of Aussie anecdotes.]
Back in the UK, his love of two wheels stayed with him, as he managed to juggle his new Digital Agency life** with racing, and after winning the BMCRC Powerbike championship he ended up in the BSB paddock racing British Superstocks, which apparently is a fairly decent level.
[** – Which is why this website looks rather more professional than youâd expect for a guy who fixes push-bikes out of his garage, he just canât help himself.]
As the accidents on track became faster and took longer to heal, he returned to the pedal powered variety of two wheels, and once again, he was hooked.
Elated to be back on a âproperâ mountain bike, his rides got longer and more adventurous, the term âdownhill trailsâ started appearing in his vocabulary, and I couldnât help but notice a growing number of cuts and grazes on his shins.
âOh yeah, I fell off my bike again.â He shrugged off.
âFell off???â
âAgain???â
âWhy are you falling off your bike, youâre 50 not 5???â I shrieked!
It turns out the Surrey Hills is the âMorzine of the UKâ, and we have the mountain biking highlights of Peaslake and Rogate right on our doorstep. Apparently people travel in from all over, just to throw themselves and their bikes down some very steep trails, jumping over features as they go! Who knew?

Soon enough, the growing number of Trail Toddlers were meeting up every week, the WhatsApp group lighting up with footage of their latest jumps, crashes and smashed phones.
Grahamâs mechanical knowledge grew with his own repairs, aided by the growing stream of friends and other Trail Toddlers with broken and bent bikes that needed some TLC. He also returned to his youth and built a bike from scavenged parts from Ebay; The Transition Sentinel was born!
So when he finally decided he had built enough websites and wanted to âexit stage leftâ from the corporate merry-go-round of Zoom & Teams calls, his thoughts turned to next steps and he decided heâd love to ease into semi-retirement with a small home-based business: So Grimâs Bikes was created to support his growing network of likeminded lunatics who also like to throw themselves down steep trails every weekend.
He is now Cytech qualified and ready to help get your bike back on the road⊠or trail, whichever you prefer.
There will also be trips to actual Morzine and Bike Park Wales⊠hopefully next time without the additional one week at the hospital in Merthyr Tydfil.
And me? Iâm all in favour of this new venture, as he is never happier than when pottering in his garage, grinning like a small child, with grazed knees to match.
I on the other hand, will be focusing on my new Substack writing project, Off on a Tangent [https://katedarracott.substack.com] from the safety of the kitchen table.
Ride safe!

Important note:
If youâre going to Bike Park Wales soon, you might like to read Grahamâs 1-star review of the Corned Beef Hash at the local Hospital. And please bear it in mind when deciding whether or not to go for that âone last runâ of the day.
