Delivery was a little longer than originally expected as the team were ensuring their new Go+ units met their standards. However, in the end I didn't mind the slightly longer wait... and it was worth it! Installation on my Trek bike was really easy and took no more than 45min from start to finish. I wanted it to make the hills to and from work a bit easier... and it hasn't disappointed. Cycled to work for the first time yesterday with the new electric powered Trek and it's made the commute so much more enjoyable and the hills are barely noticeable now.. which is no mean thing given I have a 130m altitude gain in each direction. Overall, great item and worth the wait!
