Product Description

We’re proud to be recognised by Cycling News as one of the "Bicycle Companies We Trust". Our classic, steel-frame bikes are designed and built to order in the UK, using carefully selected components sourced from around the world. Purpose-built for commuters, they combine timeless style with everyday practicality.

Sleek and minimalist, and with a 44/16 ratio, they are perfect for everyday urban bike riding. They are responsive, light, and fast and easy to maintain and use. Our single speed bikes can be ridden fixed gear (fixie) or as a single-speed with a freewheel sprocket as each bike is supplied with a flip-flop hub so the rider can choose what they prefer and change back at any time.

The Imperial Stealth is the same high specification 4130 chromoly frame as the Varsity but the frame is electroplated in chrome for a unique finish. with the Stealth version choose to upgrade front, back or both wheels to our tri-spoke magnesium wheels. The striking skeleton saddle & a 'Stealth' head cap Contrasting black components complete the look that will set you apart from the crowd. This quick, low maintenance bike is the ultimate headturner!

The MK2 has a Quella 3 spoke Quella Aero Alloy Mag Wheel on the front. Made from Aluminium and Magnesium the wheels give a striking finish to the bike

The Courier range is the origin of the brand, fast Streetwise Urban Bikes, that utilises bull horn style bars and straight stem matched with our racing saddle for a more sports/aggressive riding style. If you prefer are more upright/easy riding style then check-out our 'Classic' model with riser style handlebars.

Good, should come with instructions on how to put it together

Hi Ryheen, thank you for your review. We send information in the literature with every bike, it provides a link to our online video. After many years of selling thousands of bikes we have found the video much more effective and less impactful on the environments from our customers perspective. Visually seeing how to set-up the bike certainly helps rather than the written word for most, as some of the terms in 'bike world speak' cannot be understood by all. Also, for many they prefer bikes to built by mechanics, which always tends to be a preference and provides further reassurance that the bike has been built correctly. Mechanics will also request a 6 week follow-up to ensure that all is operating effectively and the torque remains accurate. Rather like a new car, quite often a 500 mile service is required just to ensure the smooth running of the vehicle. We are also very happy to help over a call on 0333 400 2400, do feel free to contact us.
