Ok, geek time. I've been recording every ride and every charge for my series one MX, over 160 hours of riding and 98 rides.
I though that terrain would make a huge difference. It does.
Rides round here tend to be:
Hardpark - gravel forest roads and fast trail rides
Mud - slippery sloppy bush
Sand - as much shingle as sand, pretty loose stuff
I've normalised each record to estimate what the range would have been if I kept going until the battery was at 10%.
Terrain type | Number of rides | Average distance to 10%, kilometres |
Hardpack | 18 | 56 |
Mixed | 23 | 50 |
Mud | 24 | 41 |
Sand | 33 | 35 |
So yeah, sand is hard on the battery. Mud doesn't help.
And some simple correlations to the conditions:
Terrain Type | 0.64 |
Average speed | 0.24 |
Height | 0.67 |
Average speed isn't affecting range much, but that could be coz even when I'm going fast I don't ride that fast.
Height climbed matters as much as terrain type. Basically, any time where you're on the throttle and not making much distance from that is going to hurt range. That could be ploughing through deep sand or mud, it could be coz you're dragging all that weight up a hill.
Highest range I've managed was 61 km on twisty forest roads, average speed 24 km/h. Got home with 6%.
