Ive just started using the Boardman adv 8.9e as my commuter
The motor is more than enough for me, ive only ridden it on “river” mode so far
6 x 9.5 mile commutes. it made 4 of those before needing recharging. taken me from ~42mins to ~36mins, theres a good 430 ft of climbing both ways. Definitely takes the sting out of the hills, and makes pulling away a breeze. the transition to 100% human power is noticible but not like hitting a brick wall.
I’m planning on tweaking the profiles a little, and a bit of experimenting, river to work, breeze home.. I want the legwork, but also need the speed and to be bale to get ot work without being ready for bed 😀
