Design Analysis of Battery-Operated Cargo Bicycle with Adjustable Cargo Space

Abstract

An electric cargo cycle which contains an adjustable frame, for changing the size of the cargo space, as well as the bike length is designed and developed. The developed prototype is built by using a normal bicycle as the base, with addition of a self-designed frame for the purpose of carrying cargo bucket. The developed design has a weight of 70 kg with 240 cm, 95 cm and 40 cm as length height and width respectively. The designed cargo bike has a load carrying capacity of 120 kg. The design is powered with 250 W electric motor and can move with maximum speed of 25km/hr. The steering mechanism is rocker arms based. The steering mechanism, cargo bucket and the base frame are made in two parts for commuter convenience. The cargo bucket is front mounted, on a sliding frame that enables one half of the bucket to be slid into the other half. The design has both electric and non-electric driving modes. The design find application for delivering goods, usage for short transport of goods, and industrial work. Also, the electric driven feature helps in climbing elevated terrain and reduces fatigue during the load carrying. Testing of the product was made and was found suitable for the designed parameters
