My wife has a cube reaction hardtail, she loves it, she can go anywhere a normal bike can go, and she’s never had a problem with battery range.
Ive also used it, to ride home after a 12hr shift at work, 33 miles to get home, I managed it just fine, wearing shirt, tie, dress trousers and shoes, no special cycle clothing at all.
I went camping on it, rack and panniers fully loaded, did 35 miles that trip on hilly terrain.
We’ve never used more than half the battery, its worth mentioning that I weigh 20 stone.
The cube bikes use the bosch motor, it is brilliant.
My wife likes hers so much that she offered to buy one for me, i was happy to accept.
Ive probably ridden more in the last six months than i have in years, and im sure many other people will tell you the same thing.
