Hello, last week I collected my new Trek Superfly 4 ebike. Went out for a ride today with a mate who has a Cube Acid. His bike is 6 months old. Both have Bosch engines - his is Active line plus and mine is Performance CX. Both are 500 W. I travelled 3 miles to meet him; he travelled 3 miles to meet me. We then did 20 miles. We were mirroring each other's mode performance - approximately 2/3 in ECO and 1/3 in Tour. After 20 miles his range read 72 in ECO and mine read 53 in ECO.
Anybody got any idea why the disparity? I would have thought they would have been fairly similar given that his bike is only 6 months old and mine is brand new. Obviously, his has been through a large number of charge cycles and mine has only been through one (a top up). Is there any sort of "memory" occurring here?
The bikes are very similar in weight. They've got similar tyres and both are 29ers. I don't think the different motors (Active line and Performance CX) would result in such a large difference.
One difference is that I travelled 3 miles against a very strong head wind to reach him whereas he mostly coasted down hill. That might account for a partial difference but a 19 mile range difference over a shared distance of 20 miles seems a bit odd.
The other difference is that his bike came with a 4 amp charger but mine came with a 2 amp charger (apparently that's what Trek are sending now). But given that both bikes were fully charged before setting off, surely the charge rate wouldn't affect the resulting range?
I must say, although I'm enjoying the bike immensely, I'm a bit disappointed in this range difference. I would love to hear from anyone who has any ideas as to why there was such a big disparity.
Many thanks.
