This document provides assembly instructions for City Bicycles from Bikester, focusing on the initial setup required after delivery. The manual guides users through unpacking, front wheel assembly, handlebar and stem adjustment, saddle and seatpost mounting, pedal fitting, and final checks before the first ride.
Function Description:
The manual serves as a comprehensive guide for the initial assembly of a new city bicycle. It details the steps necessary to prepare the bike for its first use, assuming that expert bike mechanics have already performed the main assembly, fine adjustments, and functional checks. The user's role primarily involves installing components that were dismantled for transport, such as the front wheel, saddle, pedals, and adjusting the handlebars. The instructions are designed to be easy to follow, even for individuals without prior experience or knowledge in bike assembly.
Important Technical Specifications (implied from instructions):
- Frame Number: Each bike has a unique stamped identification number, typically found in the bottom bracket area, but potentially on the seat tube, head tube, or fork end. Users are advised to record this number.
- Brake Setup: All bike models come with an EU standard brake setup, which may need to be reversed to comply with UK cycling standards.
- Lighting Systems: Bicycles without lighting systems do not comply with Road Vehicle Lighting Regulations after sunset. Satisfactory lights and reflectors must be fitted for night use on public roads.
- Quick Release System: Front wheels can be secured with a quick-release mechanism. The quick-release lever should be positioned on the right side for disc brakes and typically on the left for rim brakes. The clamping nut requires adjustment to ensure proper tension.
- Screw Axle System: Some front wheels use a screw axle with axle nuts. These require a 15mm open-end spanner for tightening, ensuring washers are on both sides and nuts are evenly fixed.
- Thru-Axle System: For thru-axle front wheels (12, 15, or 20 mm diameter), the thru-axle is inserted through the fork end and hub, then screwed firmly until free of play. Thru-axles require lower closing forces than quick releases or screw axles.
- Brake Types: The manual covers V-brakes, disc brakes (hydraulic or mechanical), road bike rim brakes, hydraulic Magura rim brakes, and roller brakes. Each type has specific preparation and re-installation steps.
- Handlebar/Stem Systems:
- Ahead Stem & Headset Bearings: The stem is clamped with two outer screws on the fork steerer, and the headset bearing is adjusted with a top screw. Proper alignment with the front wheel and adjustment of bearing clearance are crucial.
- Quill Stem & Threaded Headset: This system allows for good handlebar height adjustability. The quill stem has a clamping cone inserted into the steerer tube. The stem must not be positioned above its limit mark.
- Pedal Threads: Pedals are side-specific (left pedal for left crank, right pedal for right crank) with distinct threads. Forcibly mounting them incorrectly will damage the crank thread. Pedals require a 15mm wrench or 6/8mm Allen key for tightening.
- Lubrication: Metal seatposts and frames should be lubricated with assembly grease. Carbon seatposts or frames require carbon assembly paste.
- Seatpost Insertion Depth: A minimum insertion depth is marked on the seatpost. Failure to meet this depth can damage the seatpost and frame, leading to safety risks.
Usage Features:
- Step-by-Step Guidance: The manual provides clear, illustrated, step-by-step instructions for each assembly task, making it accessible for users of all experience levels.
- Tool Inclusion: Necessary tools and components are stored in an accessory box within the bike package.
- Safety Warnings: Important safety warnings are highlighted with an exclamation mark symbol, drawing attention to critical steps like avoiding contact with disc brake rotors, ensuring proper spring orientation for quick releases, and correct tightening procedures.
- Brake System Specificity: Instructions are tailored to different brake and front wheel types, ensuring users follow the correct procedure for their specific model.
- Handlebar Adjustment: Users are guided to adjust handlebars to a comfortable riding position, ensuring they are centered and tightened evenly.
- Saddle Height Adjustment: A guideline for saddle height is provided (upper edge of hip bone in line with the saddle when standing next to the bike), with the final adjustment to be made after pedals are mounted, ensuring the leg is straight when the heel is on the pedal at 6 o'clock.
- First Test Ride Recommendation: A short, quiet, and distraction-free track is recommended for the first test ride to familiarize with the bike's functions and handling.
Maintenance Features:
- Initial Inspection: An initial inspection by a bicycle workshop is highly recommended after approximately 100 km or 6 weeks of use. This allows for readjustment of mechanical components after a running-in period.
- Regular Inspections: Regular inspections are advised: after 100 km/6 weeks, 500 km/6 months, 1000 km/1 year, 2000 km/2 years, and then annually. These inspections ensure maximum service life and riding pleasure.
- Pedal Check: After the first ride, pedals should be re-checked and tightened if necessary to prevent crank damage from loose pedals.
- Tightening Torque: The manual emphasizes uniform tightening torque for pre-clamp bolts on handlebars and advises against excessive force, suggesting a suitable torque wrench for handlebar clamp bolts according to the manufacturer's specifications.
