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.

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.

I chose the straight 44mm Headset "standard" for several reasons. They are straight and keep a simple look, while hiding their versatility. The S.H.I.S. measuring standard is 44.0mm top and bottom. This is now a very common standard taking Zero Stack 44mm (ZS44) top or bottom cups and the External Cup 44mm (EC44) bottom cup. In SHIS codes 44/44 allows for both Tapered Carbon fork steerers using ZS44/EC44 and is backward compatible with straight steerers with either a crown reducer or a ZS44/ZS44 headset. 

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.

I have been a Product Designer for 25+years. I ended up working for companies wanting to transfer their production to Asia. Working with a supplier is a relationship. They want to make product to keep their factory busy so they can pay their workers fairly. We have selected one of the best Titanium factories in China. They are close to the Titanium Mills and can hydroform the tubes, CNC solid Titanium inhouse and have skilled welders. Their staff are cyclists so they have a indoor BMX track for their staff to test bikes.
