Does the Stern' need a lot of maintenance?
- No, it is very simple: mainly a rinse with a hosepipe. Now and then, check a few screws and put some WD-40 in the bearings and suspension. That's all.
Is the Stern' waterproof?
- Yes, it is even submersible.
Is the integrated battery waterproof?
- Yes, against rain, splashes and puddles.
How long do the tyres last?
- Thousands of kilometres. What wears them most: riding fast on tarmac in summer.
How do you change a tyre?
- The rim unscrews into two halves: no need to lever the tyre off with a screwdriver.
How much do the tyres cost?
- They are on sale in the shop, at the cost price we pay our suppliers: €40 a pair.
What about punctures?
- Very rare. At the front, they are standard 10-inch inner tubes: if you get a puncture, a squirt of puncture-repair spray and you are off again, and a new tube costs a few euros in any DIY shop. At the rear, the tyre is tubeless, with sealant: you don't get punctures at the rear.
What about after-sales service?
- We have all the parts and do everything in our workshop. For any question, call Adrien: his number is on the Contact page.
