The best car bike rack for most UK cyclists is a towbar-mounted platform rack. It is easy to load at roughly waist height, keeps bikes stable and can suit heavier e-bikes. A roof-mounted rack is a lower-cost option, while a rear-mounted boot rack is useful when the car has no towbar or roof bars.
This comparison covers seven products for two, three and four bikes. It includes current retailer or manufacturer listings checked on 9 September 2026, plus the BikeRadar test price for the Thule ProRide 598. For a broader overview, see our bike rack for car reviews.
There is no single rack that suits every car and every bike. Before buying, check the car’s mounting points and the compatibility of the rack and bikes, including bike weight, rear-light visibility and access to the boot.

Prices above are listed retailer or manufacturer prices, except for the £117.50 BikeRadar test price for the Thule ProRide 598. Halfords lists fitting at £30 for its roof rack and £45 for the listed four-bike towbar racks.
For two bikes, the best value depends on whether the car has a towbar. The Thule 970 Xpress 2-bike towball carrier is listed by Tredz at £84.99, making it the cheapest towbar-mounted option in this comparison. It is a sensible starting point for two ordinary bikes when simple transport matters more than premium features.
For heavier e-bikes, the Thule EasyFold 3 2-bike carrier is the more appropriate type of product. Thule UK lists it at £849.99 and describes it as optimised for heavy e-bikes. Thule also lists the EasyFold 3 3-bike version at £999.99, so the larger capacity comes at a higher price.
Without a towbar, the Saris Bones 2 Bike is the relevant rear-mounted alternative. Halfords lists it at £180 and shows a 4.5/5 customer rating from 285 reviews.
A three-bike towbar rack is usually the easiest three-bike solution because the bikes sit lower than they would on the roof. Thule UK lists the HangOn 3-bike tilting version at £149.99 and the basic HangOn 3-bike version at £129.99. The tilting model is the more practical choice when access to the boot matters.
For heavier bikes, Thule lists the VeloSpace 3 3-bike towbar rack at £849.99 and describes it as suitable for heavy e-bikes and mountain bikes. The EasyFold 3 3-bike carrier is listed at £999.99 by Thule UK and is also described as optimised for heavy e-bikes.
A three-bike roof-mounted rack avoids adding equipment behind the car, but loading is higher and the vehicle becomes taller. BikeRadar says roof racks that retain both wheels are taller, generally more expensive and potentially less stable, although they avoid removing and refitting wheels.
For four bikes, a towbar-mounted carrier is the clearest option among the listed products. The Thule HangOn 4-bike tilting rack is listed at £169.99 by Thule UK. Tredz lists the Thule 9708 HangOn 4-bike towball carrier at the same £169.99 price.
Halfords lists its 4-Bike Towbar Mounted Bike Rack at £350, with fitting at £45. Its Advanced 4 Bike Towbar Mounted Bike Rack is listed at a promotional £315, reduced from £420, with fitting also listed at £45.
A four-bike carrier can make rear visibility, the number plate and the rear lights harder to see. If a rear rack or its bikes obscure the lights or number plate, a lighting board may be required.
A roof-mounted bike rack is the most economical route among the listed options. Halfords lists a Roof Mount Bike Rack at £45, with fitting available for £30.
BikeRadar tested the Thule ProRide 598 at £117.50. Its stated strengths are secure holding, compatibility and suitability for bikes with mudguards; its stated weakness is price. Roof mounting works best when the driver is comfortable lifting the bike overhead and does not need frequent boot access.
A rear-mounted or boot-mounted rack is the main alternative when the car has no towbar. The Saris Bones single-bike rack is listed by Halfords at £59.99 and carries a 4.0/5 rating from 361 reviews. The Saris Bones 2 Bike is listed at £180 with a 4.5/5 rating from 285 reviews.
This style can be cheaper than adding a towbar, but the straps and contact points sit directly on the vehicle. It can also affect boot access and obscure the rear lights or number plate, so it should not be selected solely because it has the lowest purchase price.
For most UK cyclists, a towbar-mounted platform rack is the strongest all-round choice. A UK buying guide identifies this type as the best overall option because it is easy to load, secure, can allow boot access when tilted and can work with e-bikes. For four standard bikes, the Thule HangOn 4-bike tilting rack is a practical listed option at £169.99.
A tilting towbar-mounted rack is generally the easiest to load because the bikes sit around waist height. The Thule HangOn 4-bike tilting rack is listed at £169.99 by Thule UK. For two bikes, the Thule 970 Xpress is listed at £84.99 by Tredz, although it is a different, simpler towball-mounted design.
For transport outside the vehicle, a stable towbar-mounted platform rack is the safest type supported by the buying guidance. Roof racks require extra attention to the vehicle’s increased height, while rear-mounted racks can affect visibility of the lights and number plate.
If the car has a towbar, the Thule 970 Xpress 2-bike carrier is listed at £84.99 by Tredz. For roof mounting, Halfords lists a roof rack at £45, with fitting at £30. Without a towbar, the Saris Bones single-bike rear rack is listed at £59.99 by Halfords.
