Here is my official spare battery carrier!

Why didn’t you strap it underneath the top tube ? Was it because the strap wasnt long enough? I’m looking to buy the Bontrager adventure frame bag but I’m not sure the strap that connects to where the stem meets the down tube would be long enough.

  • The battery and bag are both too long to fit under the top tube
  • The bag has Velcro straps on each end that wouldn’t reach or go around the handlebar stem
  • The bag would block my water bottle from being removable while riding
  • I tried every configuration I could and this was the only one that really fit all my criteria

Only pity it doesn't work with anything else than the diamond frame.
Stefan, I tried briefly and you’re right, it won’t fit the Lowstep. Even with no bottle holder. Especially with a PowerTube battery in it. I could maybe make it work for food where theres more flexibility in how you pack it but you’d still have no bottle holder in the designated stays.

Since I’m getting a spare Bosch Powertube battery for some planned longer touring next year, I set to some brainstorming. I didn’t want to buy a huge pannier and I didn’t want a big spend as I probably won’t use it a ton. I also wanted something that had a dual purpose. I was looking for something shaped just like the battery and suddenly thought about a tube-shaped beer can carrier. Found this Stashers 3 carrier that has large Velcro straps they suggest for carrying your beer on your bicycle! This thing also has has Velcro straps at each end and fits perfectly on the top of the tube of my Allant+7. Had to make a modification or two but I took it out for a ride around the block and this thing is very solid! I’ll probably add a bit of cushioning and of course I‘ll put 3M paint protection film around the top tube.👍

Neat work, it looks pretty solid! I purchased a rear rack and trunk bag to hold mine, your solution wouldn't work on my bike as I wouldn't clear the top tube and the battery wouldn't fit in the diamond!

It’s a specific solution that I think should work on the my specific bike for my specific need. YMMV!🤓
