It is no secret that people are getting increasingly bigger. This is mainly due to improved nutrition, education and medical care – commonly referred to as prosperity. Therefore it is irrefutable that there is a special bike market for people with an above-average body size. VICTORIA serves this market with two XXL bikes, about which you should know the following:
Large bikes have their own characteristics, it is not enough to simply upscale the design of a standard bike 1:1. The loads caused by larger and inevitably heavier riders and the extended lever ratio depending on the frame size must all be considered in XXL frame construction. Large tube diameters provide more support than small ones and help to offset the leverage ratio that becomes increasingly unfavourable with increasing length. Modified wall thicknesses enable the development of sturdy frames for large and heavy riders. And the following applies to the stem, handlebar and seat post: additional diameter increases rigidity. The starting point for any bicycle design is always the wheels. Wide tyres, corresponding rim widths and adequate air pressure create a stable and comfortable basis, 36 spokes provide sufficient stability.
The load distribution is important when calculating the maximum load that a bike can cope with: The rider weight has a different impact on the front and rear wheel depending on the seating position. If the cyclist sits very upright, then up to 90 percent of the cyclist’s weight may be on the rear wheel. Then any possible luggage must also be added to the equation. All of these factors must be considered in the bike’s design.
