Scurra Hard Enduro mountain bike has a wild take on front suspension

When Gizmag was poking around at Interbike 2013 earlier this week, we were particularly interested in finding unique products that would catch the eye of even non-cyclists. Well, when we saw Scurra's Hard Enduro mountain bike, we knew we'd hit pay dirt. The bizarre-looking bike forgoes a traditional telescopic suspension fork, and instead uses a linkage combined with a rear shock for its front suspension. The setup allows for seven inches (178 mm) of travel, along with some other claimed benefits.
Scurra founder/engineer Martin Trebichavsky was quick to point out that the two bikes on display were proof-of-concept prototypes, and that a commercial version of the Hard Enduro would be considerably simpler and lighter ... although at 33 pounds (15 kg), the existing bikes aren't obscenely overweight as it is.
The patented Trelever front suspension utilizes a pivoting parallelogram system, to link the front wheel to a stock DT Swiss M212 rear shock. That shock is located in the middle of the aluminum frame, and sits head-to-head with another identical shock, which handles the rear suspension.
Trebichavsky says that in its current form, the Trelever system weighs roughly the same as some suspension forks. It would be good to see it lose at least a bit of that weight, though, as the one bike that we lifted did feel slightly front-heavy.
Martin also told us that along with its seven inches of travel (for a 29-inch wheel), one of Trelever's other selling points is its enhanced front wheel control. It is also said to offer a minimum of suspension response lag, low unsuspended mass, and a very stable yet agile ride.
The best way to verify these claims, of course, is to try out a commercial version of the Hard Enduro for yourself. That probably won't be possible until at least next March, when the bike is scheduled to reach the market. It should be priced at a rather intimidating €9,000 (US$12,000), which will include a transport case.
For another interesting approach to mountain bike front suspensions, take a look at the Lauf leaf-style fork.
