Christmas present for my wife who needs a little help on hills. 4.4 Ah Lithium battery came charged, 5 minutes top off. Battery is about 2 lbs, 6" x 2", fits nicely on the downtube or under the seat, small profile. Boxed condition was perfect. Installed on a '05 (lighter weight than current versions) Giant Suede with cro-mo suspension forks.
40 minute set-up, a good deal of that was simple changing front tire & tube with the Schwalbe MS we had on that bike...tweaking After a few hours of test riding, decided we wanted to move the battery pack and cables, so another 20 minutes of positioning and strapping.
No time today to ride it on the hills, but had 4 different riders testing it out on the flats. My son got her hybrid over 25mph with a simple assist. Love the smooth transition from pedaling/freewheel to front hub motor assist.
Easy peasy. So far, a terrific purchase - great fun factor. We'll have it up in the hills this weekend and post a performance review.
