The battery on each Diem model is built into the frame, which means there’s no pulling it out to take it inside to charge or keeping a spare battery handy whenever you need to swap. The team did, however, assure me that should any issue arise with the battery, mechanics could undo a couple of bolts and replace the unit.
When it comes to charging and the lifetime of the 540 Wh battery in the Diem 20 and 30, and the 630 Wh unit in the Diem 10, Orbea has some pretty lofty targets for it.
The cells should keep you out on the road for more than 70 miles, depending on your level of assistance. What’s more, the company says the unit has been tested across 1,000 charge cycles, which is enough to cycle almost two times around the Earth.
