Connecting straps for use for example in sports activities and methods of attaching the connecting straps. In one example, a connection strap system includes a connecting strap and a peg strap configured to be attached to the connecting strap. An example of the connecting strap includes (a) a sleeve of webbing having a first end and a second end and having a loop at each end, each loop having a base and a free end, (b) disposed within the sleeve of webbing, a band of elastic material extending in a continuous loop, and (c) an attachment strap, adjacent each loop, configured to secure a portion of the band to the webbing at the base of each loop. In some cases, the band has a solid, polygonal cross-sectional shape. The peg strap has a peg-loop at each end.

A flexible towing device for single-track vehicles, comprising a towing element adapted for mounting on a first of single-track vehicles and comprising a flexible towing element and a lock attached to one of the ends of the flexible towing element, a locking mechanism assembly adapted for mounting on a second of single-track vehicles and comprising a first portion of the body comprising a half-seat, a second portion of the body comprising a half-seat, which half-seats of the first and the second portion, respectively, form a seat for detachable coupling of the lock of the towing element assembly, wherein the lock of the towing element assembly is releasable from the seat of the locking element mechanism assembly following applying a release force to the lock. A towing element assembly and a locking mechanism assembly for use in the flexible towing device for single-track vehicles.

A hoverboard walker attachment apparatus to motorize a standard walker using a hoverboard. The apparatus has a principal support having a vertical stem, a pair of arms, and a hoverboard clamp attachment on a base of the principal support. The hoverboard clamp attachment is removably disposed on a hoverboard clamp disposed on a middle of a hoverboard such that it is completely fixed. A pair of walker clamps is disposed on a distal end of each of the pair of arms. Each of the pair of walker clamps is removably disposed on a leg of a walker. A user sits on a seat of the walker and places his or her feet onto a pair of platforms of the hoverboard. A kill switch is in operational communication with the hoverboard and may be disposed on the walker, wherein the kill switch is configured to cut power to the hoverboard.

The invention relates to a trailer (2) for a bicycle (1), having a braking device acting on wheel(s) (4) of the trailer (2); a sensor device (12) which supplies a measured variable, which is a measure of an acceleration force acting on the trailer (2) via a tow bar (5); a controller (18) for controlling the braking device and that is configured to act on the braking device, depending on the measured variable determined by the sensor device (12), such that an inertial force of the trailer (2) generated in the pulling mode or during braking of the bicycle (1) is compensated for or is at least reduced; and a decoupling device (10; 410; 510) which is configured for the partial mechanical decoupling of a movement of the bicycle trailer (2) with respect to the bicycle (1) in the longitudinal direction of the bicycle trailer (L).

An apparatus for providing a secondary power source for an electric vehicle and having at least one secondary electrical power storage unit for storing electrical energy for delivery to the electric vehicle as required to replace the primary power source, a power connection assembly to connect the at least one secondary power source to the electric vehicle and a control system to control supply to the electric vehicle.

Tow bar arrangement (100) for interconnection of a pulling vehicle (10) and a pulled trailer (20). The arrangement (100) comprises a control device (110) with a force sensor (111) arranged to sense an instantaneous relative force between vehicle (10) and trailer (20). The control device (110) is arranged to produce a control signal for an electric motor (21) arranged to propel the trailer (20) so that a motor force counter-acts said measured force. The invention is characterised in that the control device (110) is arranged to a first time series of force measurements, in that the control device (110) comprises a low-pass filter (112) producing a second low-pass filtered time series, and in that a regulator (113) is arranged to regulate said second time series to produce said control signal.

A pedal driven cart system combining pedals and a cart includes a shopping cart. A pedal unit is provided. The pedal unit is removably coupled to the shopping cart. Thus, the pedal unit is pedaled thereby facilitating the shopping cart to be rolled along a support surface.

A motorcycle trailer that includes a box trailer bed. The motorcycle trailer also includes a hinged lift lid, the lift lid including aerodynamic curvature on the front top and rear top. The motorcycle trailer additionally includes at least one lid latch positioned and structured on the off-road side of the hinged lift lid for fastening and unfastening the hinged lift lid closed selectively and the hinged lift lid having lid curvature corresponding to the aerodynamic curvature of the front top and the aerodynamic curvature of the rear top of the box trailer bed. The motorcycle trailer also includes the box trailer bed being affixed to a trailer frame, a road-side wheel suspended from the roadway side of the trailer frame with a road-side spring member and an off-road-side wheel suspended from the off-road side of the trailer frame with an off-road-side spring member.
