Ibis' 2nd generation Oso eMTB looks a lot like a Ripmo and comes in three travel configurations mirroring non-electric models in the lineup.
Modular platform allowing three distinct travel/geometry setups
Familiar dw-link suspension design
Size-specific wheel sizes, geometries, and kinematics
Adjustable chainstay length and rear wheel size via modular dropouts
Bosch CX Gen 5 motor with smooth power delivery and quiet operation
Lighter 600Wh battery improves handling and weight balance
Compatible with range extender for up to 850Wh
Clean aesthetics similar to Ripmo and Ripley
Motor not the most powerful on the market
Original Oso's looks were polarizing
Frame-only price not listed for HD and TR
Range extender cost not specified

All models are powered by a Bosch CX 5 motor with a 600Wh battery keeping the weight centered and low for better handling - with the option to add the 250Wh PowerMore for a total of 850Wh when you want to go further.

I had low expectations for this bike - despite an old adage we all learned in elementary school.
