Abstract
An electric bicycle and electric bicycle frame including batteries stored in a pair of substantially parallel top tubes. In some cases, the top tubes extend rearward of the bicycle seat tube, and an electronics housing may be disposed between the rearward extending top tube portions.
Claims17
An electric bicycle, comprising:
- a frame, including:
- a head tube;
- an upper top tube extending generally rearward from an upper portion of the head tube and containing a first battery;
- a lower top tube extending generally rearward from a portion of the frame beneath the upper portion of the head tube, oriented substantially parallel to the first top tube and containing a second battery;
- a down tube extending generally downward and rearward from the lower portion of the head tube;
- a seat tube that intersects the upper top tube, the lower top tube and the down tube;
- a fork extending generally downward from the lower portion of the head tube and providing a pair of front wheel dropouts;
- a pair of seat stays extending generally downward and rearward from an upper portion of the seat tube;
- and
- a pair of chain stays extending generally rearward from a lower portion of the seat tube to form a pair of rear wheel dropouts in conjunction with the seat stays;
- a front wheel;
- a rear wheel;
- and
- an electronics housing disposed between the upper top tube and the lower top tube and rearward of the seat tube;
- wherein the batteries are configured to provide locomotive power to the electric bicycle;
- and
- wherein each top tube extends rearward beyond its intersection with the seat tube.

An electric bicycle, comprising:
- a down tube;
- a seat tube intersecting a lower portion of the down tube at a bottom bracket region;
- a pair of chain stays each extending backward from the bottom bracket region to a rear wheel dropout;
- a pair of seat stays each extending generally upward and forward from a corresponding one of the rear wheel dropouts to intersect the seat tube;
- a head tube having a lower portion that intersects an upper portion of the down tube and which is configured to receive a bicycle fork steerer tube, and an upper portion which is configured to receive a bicycle handlebar stem;
- a first top tube extending between either the lower portion of the head tube or an upper portion of the down tube and the seat tube;
- a second top tube extending between the upper portion of the head tube and the seat tube;
- and
- an electronics housing disposed between the first and second top tubes and configured to be electrically connected to batteries stored within the top tubes;
- wherein the first and second top tubes are each configured to hold a battery for powering an electric motor of the bicycle.
