The Tonaros have about the same power as a Big Bear, but, being crank-drive, they can handle the extremely steep hills better. The enduro weighs 25kg compared with the Big Bear's 26kg. They're both relatively heavy bikes. The Enduro has Rockshox Dart forks, which are not bad at all. You get the same crunchy downward gear-changing as most CD bikes with the Tonaro, but it's not a deal breaker. Everything has advantages and disadvantages. You have to find a bike that suits your taste. You can't choose on specification.
