Folding and Unfolding
The Jack was is designed to go on any pace you select and in order to rotate on anything in the way. Forget about leaving behind your downtown bike in that bicycle garage and getting scratched and nicked. The Jack is manufactured with the solid 7005 aluminum frame and oversize Schwalbe Big Apple tires. Obviously the big tires can help you enjoy the ride better than 20-inch folders, but they also make the bike bulkier and heavier. Having said that, it is still lighter than many small folding bikes and fortunately it still manages to fit inside my car trunk.
The folding/unfolding process is also not as easy as other Dahon folding bikes. The frame hinge is a little stiff and you will always need to bring the included 3-way wrench to adjust the handlebar.
The Jack get 7 gears, it is enough for many riders and also eases the maintenance. If you hate small folding bikes, this is just a perfect choice. While Jack is mainly an urban bike, still it has greater potentials, it can be used for quick commuting around the city, for a short trip towards the café, an evening ride inside park or even touring. This is actually a reliable bike. If you compare it to tiny and expensive Brompton bikes, this is an incredibly good value. Apart from the bulky size, the Jack D7 is obviously more aesthetically pleasing and will also deal with potholes a lot better. I also love that Dahon equip the bike with Raceguard puncture protection on the tires and integrated seatpost pump, it will guarantee you hardly have flat tires during your rides.
The Jack D7 is not really designed for high speed, my average speed is almost the same as on smaller folding bikes while the maximum speed is just a little faster. However, due to its stability as well as durability we all realize that Jack can be the best companion of a man in busy urban roads and rural areas.
- There is no need for an extra car rack as it easily fits within the trunk
