Is the Bosch system really stupid enough that I need to go to a service agent to find the number of recharge cycles on a battery? I hope not, but can't see how to find it on the Intuvia display. If so, is this because of bad design or cynical lock-in?
I have had my Trek/Performance CX/500W/Intuvia bike for 18 months now. Shortly after taking delivery, with a fully charged battery, I rode a 10 mile circuit. I then recorded the power consumed (24 miles of a theoretical 103 miles on Eco - having first reset the range).
10 / 24 x 103 = 43 miles - the theoretical maximum range on a fully charged battery. Many rides since then have proved that figure to be pretty accurate - in hilly Wales I actually get about 42 miles from a full charge.
Every 6 months I carry out the same calculation. After one year it was 40 miles but at 18 months the calculation had dropped to 34 miles and so I set out on a longer ride to check it. After 35.35 miles, less than a mile from home, the system shut down! So again, the calculation proved to be pretty accurate.
It represents a 16% loss of capacity over 18 months/6,000 miles. If that rate of loss is linear it should take about 4 years to to reach the 60% capacity Bosch guarantee after 2 years which would still get me about 25 miles range. That's reasonable, I reckon.
Well, that's my (nerdy) way of doing it!
Also... In all that time the Bosch motor has performed faultlessly, only requiring the motor mount nuts/torx to be tightened to stop it creaking. And the rest of the bike is still good - one rear wheel bearing replaced, plus, of course, chains, drive rings and cassette.
