A mobile power pack fixed in a steering pipe of a bicycle includes a housing, a quick lock device, a fixing assembly, a mobile power source and a cover. The quick lock device is mounted on the connecting portion of the housing. The fixing assembly has a first fixing member inserted through the second receiving chamber and exposed out of the connecting portion to lock with the quick lock device, and first fixing member is screwed in the second fixing member. The quick release blocks of the quick lock device are pushed outward by the first fixing member to press against an inner surface of the steering pipe, so that the mobile power pack can be fixed in or released from a first receiving chamber of the steering pipe by the housing.

The present utility model discloses a two wheel electric motorized cycle frame incorporating a case-free battery, including a frame main body with a battery containment framework disposed on the frame main body. The battery is contained by the battery containment framework. At least one side of the framework is removable to facilitate replacing the battery, and partition boards are inserted in the framework to separate out a protective cavity for electrical connections. According to the present utility model, the battery is placed in the battery containment framework, so that a battery case is omitted. The battery is safely fixed in the framework, and one side of the framework is removable to facilitate replacing the battery. Furthermore, the partition boards are disposed in the framework to separate out the protective cavity for electrical connections of battery cables, thereby solving the problem that the battery cables are exposed to the outside and cannot be effectively accommodated due to replacement of an enclosed battery case with an open framework.

Techniques are disclosed for systems and methods associated with a micromobility transit vehicle battery connection and lock. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a frame, a battery configured to be received at least partially within the frame, and a battery lock within the frame. The frame may include a downtube having a recess disposed therein. The battery may be configured to be received within the downtube and the recess to establish a continuous surface comprising one or more outer surfaces of the downtube and one or more outer surfaces of the battery. The battery lock may be positioned within the recess and configured to engage the battery to lock the battery in place.

A modular electric bicycle with the classic diamond frame design which has been designed to accommodate a d-c rechargeable battery pack within its top, down and seat tube and conceal all electrical wiring inside the frame. The modular electric bicycle has been designed in order to ease the maintenance of electronic components and replace obsolete electronics just as easily as conventional bicycles can have mechanical components replaced.

A method of manufacturing a frame of a bike having a front wheel, a rear wheel, a saddle, a fork, and a bottom bracket includes the steps of providing a sheet-shaped element, cutting the sheet-shaped element along at least a predetermined shape to form at least one shaped sheet-shaped element, and bending of the shaped sheet-shaped element around at least one bending line to produce a bent sheet-shaped element, which defines a frame. The sheet-shaped element has a pair of substantially flat portions with an edge in correspondence of the at least one bending line, the portions of such pair being reciprocally faced and spaced apart at a predetermined distance.
