Changing inner-tubes on the small wheels of the Brompton is always a bit of a pain. Using Marathons and Marathon Plus tyres seems to have greatly reduced the number of punctures but what if it happens. Out come the extra strong tyre levers and all that swearing and faffing trying to get the tyre back on.
Well today I have the solution.
The Clown bike is a little bit heavy for the front of the pack, perhaps it would fit better on a rear rack, but it is very strong, has a very low gear for climbing (it has a very low everything really) and it has solid tyres so you'll not get another puncture while you cycle on with the Brompton on your back.
