The Complete Guide to Buying Used Bike Parts on eBay

For the professional bicycle repairer or DIY expert there is an option from eBay to buy used bike parts as stand-alone items to replace the parts on an existing bike and avoid the expense of a new bike. If a bike is damaged or dented and needs repairing then used spare parts may be available to suit the bike. Similarly vintage and retro accessories and bike parts may be available to customise it and change the style, colour, frame or parts to look more individual with items bought separately or as a job lot.

When planning to buy used bike parts they may be slightly dented or rusty so this should be assessed. Similarly any damage, frozen parts or limitations, squeaks, ability to change gears and age of the tyres and tubes should be asked of the seller and whether the bike has ever been in an accident before committing to a purchase.

Individual used bike parts may include any of the following

  • Frames
  • Forks
  • Rims
  • Wheels
  • Handlebars
  • Pedals
  • Saddles and seatposts
  • Brakes
  • Vintage parts and more

    Those who know their carbon from their vintage and their ‘Barracuda’ from their ‘Vintage Lucas King of the Road’ and are interested in carbon, old school, retro or chunky for BMX, Mountain or other used bikes should then research the options on eBay.

    eBay offers used spare parts for:

  • Town Bikes
  • Tandem
  • Hybrid
  • Cruiser/Lowrider
  • BMX
  • eBay recommends that all the information is read from the seller about the used bike parts or frame and any potential limitations, damage or restrictions. This could ensure awareness of any immediate repairs or future costs which may arise.
  • The bike frame is the main stability and structure of a bike and is generally made from metal or polymer materials which will determine the cost and strength. If replacing only the frame from eBay to re-assemble an existing bike, or custom design a bike, flexible options are available to purchase either a used bike or a stand-alone used bike frame

    Those who are interested in purchasing used bike parts on eBay need to think about:

  • For what bike the parts are for in order to understand the right size
  • What roads or terrain are to be cycled on to determine the style and suitability
  • How the bike will be transported as this may affect the desired weight
  • The type of terrain to be covered as this may determine the shape of, for example, the bike frame that would suit.
  • The cyclist’s height would determine the type of frame, wheels and what they should be made from

    Bike Frames: Materials

    There are various different types of metal and strong materials from which the main bike frame is constructed which affect the strength, durability, weight, budget and weatherproof characteristics of the bike. The main bike frames are made from steel, aluminium, titanium, carbon fibre, thermoplastic or magnesium material.

    Bike Frame Material


    steel bike frame

    Strong, heavy and can offer shock-absorption varying in price from steel to alloy

    aluminium bike frame

    Rigid but not generally as strong as steel although can be lighter

    titanium bike frame

    Highly sought-after as light and strong but generally more expensive

    carbon bike frame

    Non-metal avoids rust, flexible to shape, light and strong but expensive and less robust


    Plastic polymer moulded to a shape


    Rarely produced but less strong than aluminium

    Getting the Bike Frame Size Right

    The frame and wheel sizes determine whether it is more suitable to a child, female or male cyclist.

    When standing astride the frame of a bicycle with the feet flat on the ground there should be an allowance of approximately 1” between the body and the top of the top tube. Children need to be able to stand with their balls of the feet on the ground and be able to reach the handlebars and the brakes for both comfort and safety. 

    The size of the bike frame needs to be assessed in order to avoid any discomfort and to allow full leg rotation with the use of the pedals. The cross bar is usually slanted forward diagonally for ladies to be able to mount easily. The seat should be able to increase or reduce in height and be adjustable. The saddle seat height must only be raised until the safety grooves appear to avoid weakening the shaft. An approximate guide to the suitable size of a bike is considered to be generally measured by the wheel size for children and the frame size and height for adults.

    Buying Bike Frames Separately on eBay

    Stand-alone bike frames can be bought or sold separately on eBay as the central metal or polymer structure without having to purchase the wheels, seat and axle.  They vary with different brand, materials and prices. The bike frame can be purchased as an independent item and can either be repaired by the parts buyer or potentially through a bicycle repair workshop. It is important to double-check that all the necessary spare parts are available, and, if not, many will be available on eBay to help reassemble the bike effectively and safely.


    Bicycles are made either with gears or without. The physical effort contributed by the cyclist can be significantly reduced when ascending or descending hills if the gears can be changed.

    Gears can vary from road bikes not generally requiring gears covering flat hard road surfaces or recreation purposes to mountain bikes which generally have a wide range of gears for minimising the effort in ascending or descending sloping hills.  Many gears are available for separate purchase on eBay.


    Handlebars can vary greatly in width and height and position or shape but are generally either raised or dropped. The lower position of the handlebars can change the centre of gravity of the cyclist to improve the streamlined position of the cyclists and cover long distances at speed. Most handlebars are slightly adjustable in terms of height and position to reach the cyclist’s comfort level.  

  • For racing bikes the handlebars are usually much lower than the saddle
  • For town bikes the handlebars tend to be much higher than the saddle

    Using Spare Parts for Bike Repairs

    It is helpful to use spare bicycle parts to help repair important to review the information listed from a used bike seller carefully and with particular reference to any frame damage, rusting chains or frozen parts which may involve repair work either by the cyclist or through an independent repair shop with additional costs.
