Dismantle, inspect and reassemble a cycle

URN: IMICY05
Business Sectors (Suites): Maintenance and Repair - Cycle
Developed by: IMI
Approved on: 30 Mar 2022

Overview

This standard is about dismantling, inspecting and reassembling a cycle. It also includes servicing components highlighted by the inspection, so the cycle is left in a safe and roadworthy condition. 

This unit does not include assembling brakes, gears or wheels, all of which are covered in separate NOS units.

In this standard the term ‘cycle’ includes pedal-propelled vehicles with two, three or four wheels. It may also include pedal-assisted e-bikes:
• Road legal up to 15.5 mph with a motor with an output of up to 250w
• E-cycles used for other purposes
