yes but if your abroad and in unfamiliar territory be nice to have , I got about 40 miles out of mine last year in lake Garda but ran out on way backYup, should take you around Jersey three times I would think...
I don't have an issue with range on my 1st Gen Rise, especially once you add the range extender.
Once got 28 Miles and 4000 ft out of just the internal 360whr last summer (off-road). I reckon 40 Miles would be achievable with the extender in same conditions.
Someone with legs in a better operating state than mine should get better than that.
