Abstract
An electrically driven bicycle includes: a driving section for driving a wheel; a battery for supplying an electric power to the driving section; and a battery case loaded with the battery and mounted onto a main frame of the bicycle, wherein the battery case is formed to have a transversal cross section that includes a recess to cover at least a part of an outer surface of the main frame, and at least a portion of the battery is inserted into an inner space on each side of the recess.
Claims12
An electrically driven bicycle comprising:
- a main frame;
- a driving section for driving a wheel;
- at least one battery supplying electric power to said driving section;
- a battery case enclosing said at least one battery and mounted on said bicycle;
- said battery case including a transverse cross section that includes a recess adapted to cover at least a part of an outer surface of a structural support member of said main frame;
- and
- wherein said at least one battery includes a first battery pack having a plurality of batteries, and at least two second battery packs each having a plurality of batteries;
- said battery case including a protrusion opposite said recess;
- said first battery pack being inserted into an inner space of said protrusion;
- and
- each of said at least two secondary battery packs being respectively inserted into battery case inner space on each side of said recess wherein said at least two second battery packs are closer to each other in a direction towards said first battery pack.

An electrically driven bicycle comprising:
- a main frame;
- a driving section for driving a wheel;
- batteries for supplying electric power to said driving section;
- a battery case enclosing said batteries and mounted on said bicycle;
- said battery case including a transverse cross section that includes a recess adapted to cover at least a part of an outer surface of a structural support member of said main frame;
- a saddle;
- said main frame includes a standing pipe and a main pipe;
- said standing pipe extending obliquely in a downward and forward direction from said saddle;
- said main pipe being connected by a connecting part to said standing pipe and extending obliquely in an upward and forward direction from said connecting part;
- said electrically driven bicycle further comprising a chain case and a mounting platform, said chain case extending toward a rear wheel from said connecting part of said standing pipe and said main pipe;
- and
- said mounting platform being disposed at said connecting part and serving to mount said battery case on said standing pipe by mounting a lower end of said battery case on said mounting platform, the battery case being provided with a narrow portion and a wide portion, the narrow portion being disposed at the lower end of the battery case and formed to have a width smaller than that of an upper portion of the battery case in a right-and-left direction so as not to interfere with the chain case, the narrow portion being provided with an output terminal for the batteries, the wide portion being disposed at the upper portion of the battery case and extending above the chain case, the batteries being inserted into an inner space of the wide portion so that the batteries are substantially symmetrical with respect to a central plane formed by a center line of the standing pipe and a center.
