Olsen Bikes
In 2021 Olsen Bikes launched our Titanium frames covering a range of geometries from Gravel to Enduro.
In 2025 we have redesigned our Frames to concentrate on our Pinion Bikes. We have gone all out Pinion, as we believe in a drivetrain that lasts more than one season.
PINION EQUIPPED MOUNTAIN BIKES
A central, low centre of gravity for excellent handling and unrivalled riding dynamics, minimal maintenance, and a superior, perfectly graduated gear range – mountain bikes with Pinion gearboxes are made tough for your next offroad adventure. Whether it’s a multi-day tour, a demanding enduro stage, or a World Cup downhill course, Pinion shifting is the definition of consistent and reliable performance.

At OLSEN HQ I put a lot of emphasis on designing the RocknRollout Dropout to work with GATES Carbondrive BELTS. I have developed this on and off over 5years getting the micro tension just right...
Gates Carbondrive brings you Olsen Bikes that are:
CLEAN - Just hose off and ride.
QUIET - The antidote to a high-tech world.
LOW MAINTENANCE - Fit and forget for 10,000 miles.
rocknrollout
The RocknRollout Dropout is at the heart of the OLSEN frame design. We have focused our design around the rear derailleur dropout, but taken it further. Most bicycle frames have replaceable dropouts, but they do not allow for anything other than a derailleur. This idea came from the fact that UK riders often have a winter bike, which is often single-speed.
The RocknRollout Dropouts turn 1 Bike into 2 Bikes giving the rider more versatility. Summer bike with derailleur; winter bike as single-speed or internal gear hub.
who is olsen bikes
My name is Steven Olsen. I worked with other cycling brands like On-One Bikes and Cooper Bikes, before starting my own brand OLSEN BIKES. I have always loved mountain biking and discovered single-speed MTBing after a crash in the middle of the Karapoti Classic 50km MTB race. Many years later, after a year of Off-road commuting for 30 miles (2+hours) per day, I started to design bikes for long distance.
Olsen Bikes offer bikes suitable for everything from Singletrack Trail riding to Bikepacking adventures and beyond. Whether you are Mountain Biking, Gravel Racing or want to Cyclocross, Olsen have a bike for you. The RocknRollout Dropouts tensioners run singlespeed, beltdrive, derailleur, Rohloff Speedhub, Kindernay XIV internal Hub.
