"Took the tandem on an awesome ride this weekend. 130 km in two days. Got up some trails that really a tandem has no place on... rocky single track, lots of mud, steep climbs. The Java does it all, and all with my 7 yr old son on the back enjoying every minute of it! I seriously love this bike." Simon D.
"We love our Java - we have been riding the bike for about 6 months and love the bike. The bike is great on the road or gravel it is comfortable, responsive and fast given it's adventure geometry. The build quality is first rate, we really like the dropouts and through axles, the Di2 drive train has been spot on and we are super impressed with this bike." Bill K.
