A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.
