Abstract: Systems and methods related to seat post clamp assemblies for micromobility vehicles are disclosed. A seat post clamp assembly may include a seat clamp configured to physically secure the seat post clamp assembly to a seat tube of the micromobility transit vehicle. The seat post clamp may further include a lead screw rotatable about a longitudinal axis, a plurality of securing elements, a seat adjustment lever, a clamping band, and a housing. The lead screw may comprise sets of angled threads that engage with securing elements, so that rotation of the seat adjustment lever may enable a user to increase or decrease a clamping force applied by the clamping band on the seat tube of the micromobility vehicle.

Abstract: A bottom bracket assembly with interconnected axle and crank arms. Each end of the axle has a plurality of angled surfaces and a recess formed with a depth through at least the axle perimeter and at least partially around the perimeter of the axle. Each crank arm has a slot formed a distance along the length such that the end of the crank arm is separated into two deflectable jaws. A bore is formed orthogonal to the slot and a fastener is installed in the bore, wherein the fastener has a length to span the slot in the crank arm to engage both deflectable jaws. The fastener has a shank radius that extends to a depth of the recess. Removal of the crank arm from the axle end is opposed when the fastener is in the bore.
