top: Every horsepower to kW conversion done by template was being forced into showing the same "1 kW" equivalence (regardless of the precise horsepower figure) due to the deliberately specified "0" parameter ( ⁠i.e. r=0); simply removing this last fixes this.

As engine power increased, frame ruptures became increasingly common, and by 1903 Minerva had developed an in-frame design with the engine mounted above the [[bottom bracket]], while still also offering the clip-on kit. From 1904 Minerva began focusing more on car production, and while development and production of the Minerva motorized bicycles continued through to about 1909, they became increasing a less significant part of the company.<ref name=minerva1 />As engine power increased, frame ruptures became increasingly common, and by 1903 Minerva had developed an in-frame design with the engine mounted above the [[bottom bracket]], while still also offering the clip-on kit.

In England, the ''[[Phelon & Rayner 1.75 hp|Phelon & Rayner]]'' motorized bicycle was introduced in 1901, and was sold through 1903.

As early as 1903, motorized bicycles were being fitted with larger and heavier [[Step-through frame|loop frames]] designed to specifically accommodate larger displacement engines, which produced higher speeds. These new motorbike frame designs soon incorporated a new riding position that no longer centered the rider over the pedals, but instead moved the rider's feet forward, where they rested on pegs or platforms. The new riding position was designed to increase rider comfort and control when using the motor for propulsion, and soon owners began relying on the gasoline motor for all but emergency use. Front [[Bicycle suspension|suspension]] and (on some machines) rear suspension increased control at high speeds. By 1915, some manufacturers were omitting pedal propulsion entirely, resulting in the introduction of the first true modern motorcycle.As early as 1903, motorized bicycles were being fitted with larger and heavier [[Step-through frame|loop frames]] designed to specifically accommodate larger displacement engines, which produced higher speeds.
