What'll she do (E7000 motor range) mister?

[driftmonkey]

Just wondered what the typical battery range is on an e-sommet with an E7000 motor? If you start from a full battery and use a typical mix of Eco/Trail/Boost on a ride, what sort of mileage can be expected? 50 miles?

Its elevation rather than distance that kills range. Add into that your weight and riding style and its very hard to do like for like comparisons between riders.

However I would say that if in trail mode you are probably looking at 25-30 miles range out of a 504wh battery with an elevation gain of circa 2000ft, that's what I get an I weigh 90kg kitted up. Obviously use of eco will really extend the range.

if the bike is derestricted you will get less as the motor is always assisting you.

Here is an example of a ride which left me with battery flat at the end of it, was in trail mode only for full ride.

Powering up steep hills in Boost is crippling for range. Grinding up slowly in Eco or Trail is the way to go if you want to conserve battery. Not as exciting though!

range on the E7000 is about the same as E8000 with the same 504wh battery.
(Have had both)

As R120 said, if you want to get 50miles out of it, you won't be doing any "mountain" biking.
45 miles and sub 1000ft total elevation is totally possible though if you take it easy on the assistance.

Buy a second battery and enjoy the boost!

As mentioned in another post, tyres make a massive difference.
I fitted semi slick on the rear and it rolls amazingly.

Thanks guys, good advice. I took it for a 22 mile ride at the weekend with 1500ft of climbing. Went from full battery to 2 notches left (half left). Not sure how accurate the range reading is though....

The bars aren't equal, especially the last one.

On average I get about 25 miles out of the battery. Ascent is usually about 4500/5000 feet. This range is ok for loical rides but if I travel some distance to ride its not worth my while. I bought a spare battery so I can have a longer day and ride for 5/6/7 hours.

I managed to get 40 miles and 3024ft of climbing running the battery from full to empty. ECO mode 90% and Trail for 10% of the ride. Not too bad

Firstly look at the rear tyre, I've put a semi slick on and the difference is amazing.
Secondly look at power levels, you can adjust them with an app.

Personally I think Range is a very poor measure on its own.
Ultimately the bikes support your input and it adjusts the motor input based on mode and what your doing. So cruising along flat tarmac your input will be lower so proportionally the support will be lower and this will extend your battery. I found when I rode my E Sommet on essentially cycle paths and road the other day is I was above the assist limit a lot and when I wasn't I was in Eco 100% with the Assist output on the screen showing very low assist levels hence I rode 25 miles with more than 50% as indicated (note the battery indicator is just a guide and not totally accurate).

Conversely if I ride my local trail centre (Whinlatter/Lake District) i'll get a couple of full laps of both North and South.. which is about 1100 to 1300m climbing I think and about 23ish miles in Eco about 95% of the time. I've tested the battery to exhaustion at the end of 2 laps on the "push up" path on the North final decent and got 1.5 climbs in before it died... so not that much left.

So as R120 says the main use of battery power is climbing when the motor is assisting you more, going up the power levels increases the amount of assist so in turn uses more battery.

So unfortunately distance is not a good measure on it's own.. a VERY simplified rule of thumb is to adjust your average gentle Eco range (Say 50 miles) Vs Feet Climbed and assuming 0.1667 Factor (Based on my experience of ~3000-3500 and ~25 miles ECO (Max range) with a good safety margin).

So a very Rough Rule of Thumb Calculation would be (ECO):
50 - (50 x (0.1667 x (FeetClimed/1000)))
So:
50 - (50 x (0.1667 x (3000/1000))) => 50 - (50 x (0.1667 x 3)) => 50 - (50 x 0.5) = 50- 25 = 25 Miles

So for a ride with 2K feet of climb = 0.1667 x 2 = 0.3334
50 - ( 50 x 0.3334) = 33.33 Miles

So 4K feet of Climb
50 - (50 x 0.6668) = 16.7 Miles

Or simplified right down 50 miles minus ~8.3 miles for every 1000 Ft of climb Max range in Eco.

Yeah it's not perfect and you'll get more or less depending upon numerous other variables which change my empirical 0.1667.. but it's the best I can think of that's really simple.

Here's our experience of the E7000. Elevation is very much the determining factor as opposed to distance in my opinion.
