A bicycle safety turning device for installation upon a bicycle frame lower cross bar adapted to be engaged by the bicycle front wheel fork shoulder to limit the front fork from turning so far to the left or right as to be at a right angle to the forward movement of the bicycle and cause the bicycle to jackknife while riding. More specifically, the bicycle safety turning device consists of a pair of clamp members adapted to surround the bicycle frame lower cross bar, capped with clamp plates, and a pair of bolts bringing the two clamp plates and clamp members together, the bolts also holding a striker plate against which the front fork shoulder comes in contact after the front fork has turned through an arc of 35 to 45 degrees as desired. Encountering the striker plate, the fork is prevented from further turning. The clamp members are secured against the bicycle frame lower cross bar by a frictional fit, and in addition, by a plurality of ram darts, the point of which is forced into the cross bar by tightening the bolts residing upon the clamp plates which bring the clamp members together. Alternate embodiments provide a striker bar adapted to prevent turning of differently constructed bicycle front wheel forks and modifications for mounting the invention on the fork shaft bearing tube with a striker plate dropping down to be engaged by the front wheel fork shoulder.

A bicycle safety turning device for installation upon a bicycle frame lower cross bar to prevent the bicycle front wheel from turning to a right angle to the direction of bicycle travel and causing the bicycle to jackknife by selectively limiting turning of the front wheel fork to the left and to the right, the bicycle safety turning device comprising: a striker plate adapted to be encountered by the front wheel fork to limit turning of the front wheel fork; and a pair of clamp members adapted to encircle the bicycle frame lower cross bar and a pair of clamp plates juxtaposed said pair of clamp members, said clamp plates adapted to be forcibly urged against said clamp members, said pair of clamp members and said pair of clamp plates operably attached to said striker plate to selectively position said striker plate proximate the front wheel fork, said pair of clamp members comprising members of soft metal and said pair of clamp plates comprising plates made of hardened metal, said soft metal clamp members forcibly engaging the bicycle lower cross bar to frictionally secure said clamp members and thus said striker bar to the bicycle frame lower cross bar to reduce scarring and damage to the bicycle frame lower cross bar whereby the degree of turning of the front wheel fork is selectively limited.
