Tern Vektron Q9 Review

Nov 2019

Price: $3199.00 | Model Year: 2019 | A premium folding electric bike with Bosch drive system and leading warranty, sturdy and quiet with plenty of adjustability (seat post height and stem angle), smart accessories help you carry gear and stay dry without noise

Observations
  • A premium folding electric bike with Bosch drive system and leading warranty, sturdy and quiet with plenty of adjustability (seat post height and stem angle), smart accessories help you carry gear and stay dry without noise

  • The folding joints are thick, sturdy, and don't have sharp edges, both latches have two-step locks to keep them secure and they fold flat to stay out of the way, a magnet and rubber strap keep the bike from coming unfolded

  • Excellent Schwalbe Balloon tires with puncture protection, reflective sidewalls and a larger diameter for improved comfort, you also get bright integrated lights and a delay feature for safety when parking

  • The bike costs a bit more, only comes in one size, the Purion display is not removable, and the Bosch system although wonderful, is the entry system with the Active Line motor and PowerPack 400
