Where each one wins

  • Fafrees FM8 is 1.2 kg lighter.

The Fafrees FM9 does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the Fafrees FM8 is the one to justify not buying.

Who each one is for

Fafrees FM8

Suits you if you want:

  • rated to 150 kg of rider and luggage together
  • about 38 km estimated, which covers a 19 km each-way commute

What it asks in return:

  • 40 Nm of torque, so long climbs will ask for your legs

Each line above is read straight from the specification: torque, weight, payload, battery and our range estimate. Nothing here is a preference, and neither bike is being recommended over the other.

What each one costs to own

Over 5 years the two land within 5% of each other, which is inside the error on any of these inputs. Cost is not the deciding factor here.

That figure moves mostly on the battery. The Fafrees FM8 covers about 27,840 km before its pack is due for replacement; the Fafrees FM9, about 28,800 km. Ride less than that and the replacement never enters the sum.

Five years at 3,000 km a year, from the constants published on our methodology page. Resale is subtracted, which is why it shows as a negative.

Which one to buy

  • Pick the Fafrees FM8 if you carry the bike up steps, onto a train, or into a flat.

Verdict

On the measured axes the Fafrees FM8 is the better buy, and the Fafrees FM9 needs a reason of its own: a colour, a frame, a shop you trust, a price that moves. None of those are in our numbers, and all of them are legitimate.

Range here is an estimate under one reference ride, not a measurement. Yours will differ with terrain, weight, tyres and weather, which is what the range calculator is for.
