Abstract: This paper examines reasons why wheel wobble occurs in common production bicycles. In particular, the effects of frame size, rider position and riding style are examined with reference to a range of mathematical models of bicycles which are available in the published literature. Much of the motivation for this work comes from the personal cycling experience of one of the authors and t...

This paper presents the implementation and characteristic analysis of a drive system for a three-phase permanent magnet motor with independent excitation winding that is applicable for electric bicycles. The design features improves the phase current waveform, output power, and torque by using advance angle control. This adjusts the phase angle of each phase current in relation to back EMF. In ...

Shared mobility is a service that allows users to share various transportation modes and use them with reservations when necessary. It started private automotive car-sharing ride-sharing services. Currently, it operates on wider range, including personal devices such as electric bicycles scooters. The purpose of this study derive direction for providing future shared services through analysis f...

Shared electric scooters (e-scooters) offer a potential strategy to mitigate environmental concerns and congestion. However, successfully addressing these issues with e-scooters requires adoption across diverse array of consumers. Understanding the differences between users non-users can improve shared e-scooter appeal, operation safety. The objective this paper is compare in terms their percep...

Bicycle sharing systems are increasingly popular around the world and have the potential to increase the visibility of people cycling in everyday clothing. This may in turn help normalise the image of cycling, and reduce perceptions that cycling is 'risky' or 'only for sporty people'. This paper sought to compare the use of specialist cycling clothing between users of the London bicycle sharing...

In this paper, I explore the application of various random sampling based algorithms to dynamic models of bicycles. Starting with relatively simple 3-dimensional state space models of bicycle and working up to a more realistic 7dimensional model that incorporates skidding, I examine RRT, RG-RRT, RRT*, and LQR-RRT*.
