HITWAY BK3M vs HITWAY BK6M

Where each one wins

• HITWAY BK6M is 8 km further on range.
• HITWAY BK3M is 48 Wh more battery.
• HITWAY BK6M is 1.3 kg lighter.

The HITWAY BK3M leads on 1 of these, the HITWAY BK6M on 2. Neither sweeps it, so the choice comes down to which of those you actually use.

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 HITWAY BK3M covers about 38,400 km before its pack is due for replacement; the HITWAY BK6M, about 35,840 km. Ride less than that and the replacement never enters the sum.

Which one to buy

Verdict

On the measured axes the HITWAY BK6M is the better buy, and the HITWAY BK3M 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.
