"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.
