Buying one used
What to check on a used Tern GSD S10 (Gen 3)
- Battery. New, it has a 545 Wh battery with a claimed 98 km range. Ask how far it goes on a charge now, and how old the battery is.
- Serial number. Check the frame number with a stolen-bike register before you pay, and get a receipt or a written bill of sale.
- Is it still legal? Make sure it has not been “unlocked” or fitted with a throttle kit: that makes it a motor vehicle. Compliance details.
- Compare with new. Check new and ex-demo prices before you make an offer. A demo unit with a store warranty can be the better buy.
