The Bikes Direct HAL5 series looks like it'll work for a project using Grin Tech's 9 Continent free hub motor, but I'd like to consider other bikes if there are any.
I like the HAL5 because while it's not a 4 bar suspension, at least it's not single pivot. Seems everyone's moved to thru axles- B.D.'s HAL6 and HAL Boost have them too.
The HAL5 Trail also comes with an old-fashioned 3x9 drivetrain. A crankset that's similar but with square-taper to use a Sempu torque sensing bottom bracket is available- FC-M3000 Acera.
I see that builders like Luna have moved on to Bafang mid-drives and those do eliminate the dropout compatibility problem, but I really like the silence of direct drive hub motors.
