A bicycle rollers device, having a frame that includes a rear mounting assembly for two rear rollers; a front mounting assembly for a front roller; support elements, for supporting the frame above a surface, upon which the support elements are set to rest; and a central bridge connecting the front mounting assembly to the rear mounting gear. Also, two rear rollers are mounted in the rear mounting assembly and a front roller is mounted in the front mounting assembly and defines a roller width. Finally, the central bridge is more narrow than the roller width, thereby permitting a bicycle rider to mount and dismount a bicycle set on the rollers without encountering the central bridge.

A bicycle rollers device, having a front and a back and comprising: (a) a frame including: (i) a rear roller mounting assembly for two rear rollers;(ii) a front roller mounting assembly for a front roller; and(iii) a central bridge assembly connecting said front roller mounting assembly to said rear roller mounting assembly;(b) two rear rollers mounted in said rear roller mounting assembly, and a front roller mounted in said front roller mounting assembly;(c) a set of wheels mounted on said frame so as to support said rollers above a surface upon which said wheels are set, said wheels permitting forward and rearward motion of said frame; and(d) a motion-resisting assembly, including: (i) wherein one of said set of wheels is a motion-resisting wheel, having an axis of rotation and a wheel attachment element displaced from said axis of rotation;(ii) a device attachment element on said device; and(iii) an elastic tension member, attached to said device attachment element and said wheel attachment element, wherein said motion-resisting wheel has a centered position in which said elastic tension member is at its shortest and wherein when said motion-resisting wheel rotates from said centered position said elastic tension member urges said motion-resisting wheel toward its centered position. 4. The device of claim 3, wherein said wheel attachment element is a post attached to said motion-resisting wheel, and said elastic tension member is an elastic loop, that is looped over said post. 5. The device of claim 4, wherein said post terminates in a knob that retains said elastic tension member on said post. 6. The device of claim 4, wherein said motion-resisting wheel has a circumference and said post is attached to said motion-resisting wheel by way of a rigid element attached to said motion-resisting wheel, so that said post protrudes past said wheel circumference. 7. The device of claim 3, wherein said device attachment element is a stationary axle for one of said wheels. 8. The device of claim 3, further being divided into segments that are connected together by hinges, so that said device can be folded into a compact state, and wherein said device attachment element and said motion-resisting wheel are positioned on a single one of said segments, so that said device can be folded without releasing tension on said elastic tension member. 9. The device of claim 8, wherein said motion-resisting wheel and said device attachment element are both positioned on said rear roller mounting assembly, which is hinged to said central bridge assembly. 10. The device of claim 3, wherein said elastic tension member is made of polyurethane. 11. The device of claim 3, wherein said elastic tension member acts as a damped spring.
