Fafrees F20 Master vs Fafrees FF20 Polar

Where each one wins

• Fafrees FF20 Polar is 276 Wh more battery.
• Fafrees FF20 Polar is 20 km further on range.

The Fafrees F20 Master does not lead on a single measured axis here. That does not make it the wrong bike, but it does mean the Fafrees FF20 Polar is the one to justify not buying.

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 F20 Master covers about 42,880 km before its pack is due for replacement; the Fafrees FF20 Polar, about 57,600 km. Ride less than that and the replacement never enters the sum.

Which one to buy

• Pick the Fafrees FF20 Polar if you would rather charge less often than carry less weight.

Verdict

On the measured axes the Fafrees FF20 Polar is the better buy, and the Fafrees F20 Master 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.
