The five charge level LEDs indicate the charge level. A pale blue bar corresponds to approx. 20%, a white bar approx. 10 %. In addition, the display turns orange below 30% and red below 10%. Flashing red flashing at 0 % indicates that motor support is no longer available, but that there is still reserve power for light. Source: Bosch eBike Help Center

We list a guideline tire size for each frame, but the real answer is: it depends. Tire brand, tread pattern, rim width, conditions, and how aggressively you ride all play a role. Wider rims can make tires measure larger, and there’s variability between sizes and manufacturers (not all 29” x 2.4” tires are created equal).

If you ride in mud, you'll need extra clearance to avoid packing up. If you push the bike hard, you could flex the rear wheel enough to cause tire rub on the rear triangle—even if you think you’ve got plenty of clearance.

So, what's the takeaway? Please use common sense. If your wheel is properly dished, trued, and tensioned and your tire is rubbing hard enough to damage the frame, you’re probably running too big of a tire.

This frameset is covered for life against manufacturing defects for the original owner and comes with a lifetime crash replacement policy. You can read more about our warranty and crash replacement policy on our Support Page.

Installing frame protection will not affect your warranty, but we do caution against installing it on neon or brightly-colored models as these paints are more susceptible to discoloration and fading. Paint fade is not covered under our factory warranty.
