Is it for you?
We have not ridden this bike. This read is based on the spec sheet and Australian seller information, not a test ride.

Trail riders who want a playful, shorter-travel full suspension eMTB rather than a full enduro rig.
Standout strength

What is the range of the Merida eOne-Forty 400?
The Merida eOne-Forty 400 has a claimed range of about 73 km from its 630Wh battery. Real-world range is usually lower than the claim, since it depends on assist level, rider weight, terrain and wind.
What motor does the Merida eOne-Forty 400 have?
The Merida eOne-Forty 400 uses a Shimano STePS EP801 motor, in a mid-drive position, producing 85Nm of torque. Mid-drive motors climb hills better because they work through the bike's gears.
How much does the Merida eOne-Forty 400 weigh?
