I have changed the tires (to the best Maxxis ones on the market), inner tubes, and grips, and added a front mudguard and a bottle cage.
Included with the bike: 2 inner tubes, replacement bolts for the brake discs, the charger, and the battery keys.

Also, I recently bled the brakes and changed the brake pads.

The pedals visible in the photos are not sold with the bike. Also, the bike has a sort of scratch on the frame (visible in the last photos) and following a fall, I broke the lever on the front wheel axle....
