Firefox Momentum 700c (2015) : ChooseMyBicycle.com Expert Review

The hybrid aluminium frame in the Firefox Momentum 700C 2015 is very similar to what you would get on high end hybrid bicycles, and very well finished too, but the geometry is different. It is based around a mountain bicycle geometry, with a relaxed head angle and a longer wheelbase. The result is a very stable ride when you get up to speed, and thanks to the reasonable overall weight that's quite easy to do.

The versatility of the bicycle boils down to the Suntour suspension which takes the comfort level of the bicycle up a few levels. Yes, it does add a bit of weight to the bicycle. But, the gain of it is the bumpy trail routes which the Momentum will conquer seamlessly.

The mountain bicycle characteristics are also shown by the gearing groupset choice, the Shimano Acera M191 8 speed. ¾Acera is considered an entry level option on MTB bicycles but it is for sure a high performing component on a hybrid bicycle. Because of Acera's low profile and single tension construction, the rear derailleur does not hit the chain stay in rough conditions. The front derailleur which similarly has a more compact profile, provides better clearance with the frame and wheels.

In the Tektro mechanical disc brakes on the Firefox Momentum 700C, there is no room for words like 'modulation', mostly due to the mechanical system which means all you will get is an on/off brake functioning seasoned with reduced braking power. You will have to give more time for braking if you don't want to end up in the scenery on side of the roads. During this test, the brakes were connected to a pair of Shimano levers, which weren't among the best we have used. That is why it is useful to remind ever rider that a pair of decent levers, with a bigger amount of leverage, can improve braking up to a point.

The Zoom Alloy 660mm handlebar on the Momentum is wide and curved enough for decent steering control for quick maneuvering in city traffic and enough stability on flat muddy trails.¾

The Momentum's 700Cx35C Kenda tires cope with our urban environment's ever-present poor roads and make it comfortable enough for kerb-hopping and forays on rougher surfaces. There will be an obvious discomfort felt by the rider when on long distance rides (30km+) as the weight of the bicycle starts to kick in as a negative.
