The London cycling map, in broad strokes
The river splits the city into two different cycling experiences. North of the Thames, the centre is relatively flat, the cycle lanes are denser, and most of the high-traffic commuter routes run east to west along the river corridor. South of the Thames, the terrain is hillier, the cycle network is patchier, and the commuter flow tends to run into central London from the suburbs.
Richmond Park is the city's de facto road cycling venue. The seven-mile circuit climbs gently, has almost no traffic outside peak hours, and attracts a serious cycling scene that leaves before sunrise at weekends. Regent's Park is the more central equivalent, with a flatter three-mile loop that gets busy from six in the morning.
For mountain biking, Lee Valley has the closest trails to central London, with a cross-country course and some jumps. Epping Forest sits on the north-east edge and has genuine singletrack. Swinley Forest near Bracknell is the nearest proper trail centre and is where most serious London mountain bikers actually go.
For commuting, the Cycle Superhighways CS7 running south to Clapham, CS3 along the Embankment, and the newer north-south routes are the arteries. Quietways take back streets between them. A good route into central London from a zone 2 suburb is almost always possible without touching a main road for more than a few minutes.
The London used bike market
London has a huge used bike market because the city has an estimated 730,000 regular cyclists, a constant flow of new arrivals and people leaving, and a thriving industry of couriers, delivery riders and commuters who turn over bikes frequently. Prices are generally lower than in other major UK cities for comparable used bikes, simply because supply outstrips demand.
Folding bikes, particularly Bromptons, are overrepresented in London. The combination of small flats, train commutes, and the Brompton factory being in west London all contribute. A used Brompton in good condition in London often sells within hours of being listed.
Fixed-gear and single-speed bikes are also common, partly because of the courier culture and partly because they make excellent low-maintenance commuters for the flat central area. Many of these bikes have been through several owners and the best ones have been maintained by people who knew what they were doing.
At the other end, premium road and gravel bikes sell well because London has a concentration of high-earning cyclists who upgrade regularly. If you are looking for a two-year-old carbon road bike or electronic-shifting gravel bike at a sensible price, London is where to look first.
Bike theft, and how to deal with it
London accounts for the largest share of reported bike thefts in the UK, partly because there are more bikes here, and partly because the resale market makes theft profitable. In 2024 the Metropolitan Police recorded around 18,000 reported bike thefts in London, and the real figure is higher because many owners do not report.
Bike theft in London clusters around stations, university campuses, and unsupervised bike parking at workplaces. The Overground stations in east and south London see high theft rates. University College London, King's College, and many office bike cages around the City and Canary Wharf have had theft problems despite appearing secure.
The first rule of London cycling is not to leave a bike locked on the street overnight. Every bike left outside between 10pm and 6am is a target. Home storage matters as much as lock quality.
The second rule is to use a proper lock, correctly. A Sold Secure Gold or Diamond rated D-lock through the frame and a wheel, attached to a solid immovable object, is the minimum. Two locks of different types, fitted through different parts of the bike, makes theft meaningfully harder.
The third rule is to register the bike. UK stolen-bike databases used by police forces are widely accessible and free to register on, including with the Metropolitan Police. A registered bike is significantly more likely to be returned if recovered. Cyclesite cross-checks every listing against UK stolen-bike databases before the listing goes live.
Bikes on London trains and transport
The Tube accepts folding bikes at any time with no restrictions. Full-size bikes are allowed only on the District, Circle, Hammersmith and City, and Metropolitan lines, and only outside peak hours. That makes a folding bike the single most useful type of bike for multi-modal London commuting.
Overground and the Elizabeth Line accept folding bikes at all times. Full-size bikes are allowed outside peak hours, generally before 07:30, between 09:30 and 16:00, and after 19:00. Check the specific train operator before travelling.
National Rail services into London have more mixed rules. Southern, South Western Railway, Southeastern and Great Northern all have their own restrictions. Thameslink is generally the most bike-friendly of the commuter lines. A folding bike avoids every restriction and travels as hand luggage on any train at any time.
Buses do not accept bikes, folding or otherwise. Cycling and walking are the transport options if trains and Tubes are unavailable. The river boats on the Thames Clipper allow folded bikes at the discretion of the crew.
Insurance, storage and practical ownership
Insurance in London is close to essential. Expect to pay six to twelve percent of the bike's replacement value per year for a decent policy. Cycleplan, Bikmo, Laka and the PTOS policies all cover London postcodes, though premiums are highest in central London, parts of Hackney, and Lambeth.
Storage is the practical constraint for most London cyclists. A ground floor flat with a garden, a shed, or a communal bike store solves the problem. A first or second floor flat without dedicated bike storage makes cycle ownership difficult, and a folding bike that lives inside may be the only realistic option.
Many London developments now include bike storage as part of the leasehold. Check the bike store lock quality, the access hours, and whether it is covered by building insurance before relying on it. Some managed bike cages are less secure than they appear.
Council-provided secure cycle storage, often called bike hangars, is available in most London boroughs. Waiting lists can be long but a secure on-street cycle hangar typically costs thirty to sixty pounds a year and is significantly safer than locking a bike to street furniture.
Where to buy in London, and what to watch for
Cyclesite accepts listings from all London postcodes and checks every bike against UK stolen-bike databases. Before committing to any purchase, always inspect the bike in person and check the frame number yourself as a second step.
Meet at a neutral public location during daylight hours. Stations, cafe forecourts, and well-lit car parks are sensible choices. If a seller refuses to meet at a public location, or insists on meeting only at a residential address that is not their own, walk away.
Ask for the original receipt if the seller has one. A bike without any paperwork is not automatically stolen, but it is harder to establish ownership history. A bike with original receipts, warranty cards, or service records from a named shop is easier to verify.
London has a high concentration of bike shops that will inspect a used bike for you, often for fifteen to thirty pounds. If you are buying a bike worth more than five hundred pounds, the pre-purchase inspection is a sensible spend. Shops like Brixton Cycles, Bicycle Workshop in Ladbroke Grove, Condor Cycles on Gray's Inn Road, and Mosquito Bikes in Islington all offer this service.
