Bike Sizing Guide

Choosing the right sized bike depends on the type of bike, your height, your riding style, and your preference. To get started, think about your style of riding, measure your height.

1.      The type of bike. What type of bike you choose will affect the size bike you buy.

2.      Measure your height. To find the correct sized bike you will need to measure your height and your inside leg. Measure the height from the book to the floor. If you have a positive ape index then go for the larger size, or if you have a negative ape index go for a smaller size.

Bikes are measured by their seat tube length. Mountain bikes are either measured in inches or descriptive sizes. Road bikes are in centimetres or descriptive sizes where as Hybrid bikes can be any one of the three. Bikes also get longer as they go up in size but different brands can be inherently longer or shorter than others.

Stand over height measurements are to the top of the top-tube. In theory, your stand over height is your leg measurement minus 2 cm.

Wiggle Ltd

Wiggle Ltd is an online retailer of cycle, run, swim and triathlon products, based in Portsmouth, Great Britain. Wiggle started as a small independent bike shop called Butler Cycles, located in Portsmouth. Wiggle officially started trading on the 28th May 1999, with an initial investment of £2000 by Mitch Dall and Harvey Jones. Between 2002 and 2009, Wiggle continued to experience strong progression. In 2009, Dall sold his 26 percent stake in the company to the ISIS-led buyout group. Annual sales revenue had reached £55 million.

In December 2011, the company was sold to Bridgepoint Capital for £180m. In September 2013, Stefan Barden joined Wiggle as CEO, formerly the CEO of Northern Foods, Heinz UK & Ireland and Brakes Uk & Ireland.

Since Barden's appointment, Wiggle has continued to expand at a rapid pace, in multiple business areas. In March 2015, the company appointed Brian McBride as Chairman.

In the summer of 2015, Wiggle moved its main warehouse premises to 'Citadel' - a super-warehouse in Wolverhampton, with 323,000 square feet of storage.
