Transition have two eBikes in their range, the Repeater, and the Relay (due in March 2023). The Repeater has the more powerful motor of the two (85Nm compared to 60Nm), and has a large 630wh battery for much more range.

Similarly to the Sentinel, the Repeater is a bit of a do-it-all ebike. 160 mm of travel and 29" wheels front and back help it cover ground quickly. Transition have managed to fit the motor in without straying too far from the sort of numbers you would look for in an enduro bike (455 mm chain stays, compared to 440 mm for the Sentinel and 452/454 for the Spire).

Japanese Toray carbon fibre with aluminium inserts keep the frame weight down and durability up. Transition offer a lifetime frame warranty for the first owner, as well as a crash replacement program. Main pivots use a collet for extra stiffness, and added bearing seals keep the Enduro MAX bearings running smoothly for longer. If you're not familiar with Enduro MAX bearings, they are made specifically for mountain bike suspension linkages, and they last far better than other bearings in Scottish riding conditions.

Three specification levels are available, each one has a 38 mm fork to keep the front under control. Bar rise as well as seat post drop varies depending on the size you ride.

  • Flush mounted chainstay and seat stay protection.
  • Low profile motor skid plate.
  • The 630wh Shimano battery can be removed with a 4 mm allen key.
  • SRAM UDH (Universal Derailleur Hanger).
  • Water bottle compatible.
  • Hidden cable routing.
  • Accessory mount.
