Hopefully you won’t as we have fitted each bike with top-quality puncture resistant tyres and tubes. Flat tyres can be avoided by watching where you are riding and avoiding riding in gutters and over sharp object such as broken glass. If you are concerned though we can provide you with a can of sealant / inflator that, for 90% of flat tyres, will get you moving again.
If it doesn’t work though you will unfortunately need to return the bike to us to get it repaired. (Tip: Maxi taxis will carry bicycles).
