Bikes are not allowed on Tubes. This is because of the safety concerns for both cyclists and other passengers. There have been a number of incidents where cyclists have been hit by trains, or where they have caused delays by riding on the tracks.
How To Choose Inner Tubes – GCN's Guide To Road Bike Inner Tubes
Assuming you’re asking if bikes are allowed on the London Underground (or “tube” as it’s colloquially known), the answer is yes! You can take your bike on the tube as long as you follow a few simple rules.
First, you’ll need to purchase a special ticket called an “Accompanied Bike Ticket.”
This ticket allows you to bring your bike on the tube during certain hours (weekdays from 7am-10am and 4pm-7pm) for an additional fee. You can purchase one of these tickets at any ticket office or machine.
Once you have your ticket, make sure to enter and exit the station using the designated bike entrance/exit.
And that’s it! Just be mindful of other passengers and make sure not to block walkways or escalators while on board.
Which Tube Lines Can You Take a Bike on
Bicycles are not allowed on the London Underground, with the exception of folding bikes which can be taken on board at all times. However, there are a number of cycle routes which run parallel to Tube lines, making it easy to combine cycling with public transport.
The following Tube lines have dedicated cycle routes running alongside them:
Central line – the West London Cycleway runs alongside the Central line between Woodford and Shepherds Bush
Jubilee line – Cycle Superhighway 9 runs alongside the Jubilee line between Wembley Park and Stratford

Where are Bikes Allowed on Tube?
Bikes are allowed on tube as long as they are folding bikes. There are some conditions that apply, such as the bike must be folded before you go through the ticket barrier and it must be placed in a bag. You can find more information about this on Transport for London’s website.
Is It Ok to Take a Bike on a Train?
Assuming you are asking if it is okay to take a bike on public transportation, the answer is usually yes. Most trains and buses have racks on the front or back that bikes can be secured to. It is important to make sure your bike is secure before boarding and to follow any instructions from the driver or conductor about where to place your bike.
Some transit systems require riders to purchase a special ticket or pass in order to bring a bike on board, so be sure to check the rules of the system you will be using in advance.
In general, it is best to avoid taking up more space than necessary on public transportation during busy times, so if possible, fold up your bike or carry it onto the train or bus rather than trying to find space for it in the aisle. And as always, use common courtesy and refrain from biking in areas that are off-limits or where doing so would block other passengers’ path.
Conclusion
According to the blog post, bikes are allowed on tubes in London as long as they are foldable. This is a great option for those who want to cycle but do not want to deal with the traffic. The only downside is that there are some stations that do not have elevator access, so cyclists need to be aware of this before they plan their route.
