This one just popped into my inbox and is a great deal for the UK on Bonza Bike Bags. These will be ideal for your trip to Europe for any remaining duathlon/triathlons that haven’t been cancelled and, of course, for that super-cheap European cycling holiday, you could book right now.
A mate of mine used one last year and they are the cheapest way to cover your bike for a flight somewhere. The advantage over the hard box is that you don’t go over the weight limit and so avoid paying £60/£100 or whatever it is for that (BA..grrrrr). Clearly there is less protection from the canvas sides but my mate was alright. Interesting there IS a clever internal frame that you fasten your bike onto.
The image clicks to their site and you use the code BIKEBAG60.
If you want to help me 😉 and get a hard one (ahem) then try one of these at Wiggle: the semi-rigid LifeLine looks good for your wallet at £89 but the name won’t reflect your testosterone levels 😉 Sorry, I’ll grow up now, I don’t usually do smut or bad language on this site but these are hard times.

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
