It has a brake light and a suspension fork - that's about all I got:
Belt drive?
Funny!3rd one is Kick stand ( my guess)
I will hazard a guess at an updated GSD. Gen 4 Bosch. Belt. Atlas kickstand. Brakelight. Is Is Bosch's ABS ready yet?
14 Speed hub by Rohloff ?
Maybe non-electric HSD touring version ?
A while ago I contacted Tern about their folding touring specific offerings or lack thereof .
I was told they were looking for the right drivetrain .
