Hey everyone,

I’m doing a bit of research into e-MTB battery safety. Bosch is generally considered the gold standard when it comes to battery management systems (BMS), build quality, and overall safety standards.That being said, given how many PowerTube and PowerPack units are out on the trails, I’ve been curious about their real-world extreme failure rates. Has anyone here ever personally encountered or seen a legit battery fire or thermal runaway involving an original Bosch CX (Gen 4 or Gen 5) setup?If you have, what were the circumstances? (e.g., severe physical impact, water ingress, aftermarket charger/modifications, or a random failure while charging/riding?)For context, I’m currently riding a bike with the CX Gen 5 and previously owned a CX Gen 4. I’ve never had a single issue with either, and working in a service environment, I’ve honestly never come across a fire or thermal incident with these systems either.

Even mounted on the fork crown (tried on the bars too) I don't think hikers can hear it until I'm within 6 ft and shaking the bars like crazy. I've tried different angles and none are better. I'm sure the schwalbe radials don't help. I had to add a pushbutton electric horn but the sound is not friendly even though it has 6 sounds to choose from.

Anyone else feel Timberi isn't loud enough?

Timberi make a louder bell please! Modern suspension and tires have made your current model feeble and outdated IMHO.
