Marin has added a second eBike to its range of mountain bikes; the Marin Rift Zone E. Roughly based on the Rift Zone 29 Trail Bike, the Rift Zone E rolls on a 29″ wheelset, but is boosted in the travel department to a balanced 140mm. Three aluminum models are launching today, built around the latest Shimano EP6 and EP801 Motors with a maximum battery capacity of 630 Wh, with pricing starting at $4,499 USD.

The Marin Rift Zone E Base Model retails at $4,499 USD (£4,355), fetching a RockShox 35 Silver R Fork, an X-Fusion 02 PRO R Air Shock, Shimano Deore 10-Speed Drivetrain, and TRP Slate EVO 4-Piston Brakes. This one gets the Shimano EP6 Motor and a 504 Wh battery, but can take a 630 Wh.

Marin Rift Zone E

  • Fork Travel: 140mm
  • Rear Wheel Travel: 140mm
  • Wheel Size: 29″
  • Frame Material: Aluminum
  • Sizing: S-XL
  • Battery Capacity: Up to 630 Wh
  • Starting Price: $4,499 USD
It’s worth mentioning that all models of the Marin Rift Zone E benefit from CushCore tire inserts; these vibration-damping rim-protecting inserts are worth somewhere in the region of $150 USD

The Rift Zone E is Marin’s trail-oriented eMTB with 140mm of rear wheel travel delivered by a linkage-driven single-pivot suspension platform the brand call MultiTrac. It balances that with a travel-matched 140mm fork with a 42/44mm offset. In keeping with its shorter travel numbers, the Rift Zone E has a less aggressive geometry than its longer-travel sibling; the Alpine Trail E.

The Marin Rift Zone E1 Model with its Shimano EP801 Motor and 630 Wh battery retails at $4,999 USD (£5,599). Spec highlights include a RockShox Pike Base Fork, Super Deluxe Select+ Air Shock, Shimano Deore 11 Speed Drivetrain and TRP Slate EVO 4-Piston Brakes.

This one gets a 65° head angle, a reach of 485mm on the size large, and 440mm chainstays across the S-XL size range. The seat tube angle is quoted as a consistent 77°. While some of its dimensions do match those of its acoustic sibling, the longer rear-center length makes the eMTB the bigger of the two with a much longer wheelbase of ~1247mm on the size large.

Like the more enduro-oriented Alpine Trail E that was updated last month, all three Rift Zone E models launching today benefit from CushCore Pro tire inserts and Marin tire sealant. These $150 USD vibration-damping rim-protecting inserts sit within 29″ x 2.5″ Vee Tire Co Attack HPL tires, protecting Marin’s 29mm internal width aluminum rims.

Marin Rift Zone E Kinematic

Marin says their goal with the Rift Zone E was to produce a leverage curve that allows for easy tuning Over the 140mm of travel, overall progression comes in at 24.2%.

With the anti-squat, the brand’s goal was to keep it just north of 100% around the pedalling zone. According to the graph provided, the suspension will have a slight tendency to rise up out of its travel under accelerations induced by pedalling – the data pertains to a 34T chainring and the 10T cog of the cassette.

For the anti-rise, we are told the aim was to keep it as close to 100% as possible throughout the entire stroke, in order to ensure the chassis remains stable under braking.
