Abstract

The utility model discloses a rear wheel forward-folding type folding electric bike which comprises a bike front wheel, a rear wheel, handlebars, a cross beam, a seat and a rear frame used for fixing the rear wheel. A rechargeable battery is arranged inside the cross beam and connected with a controller. The controller is connected with a rear wheel hub motor on the rear wheel. A folding device used for folding the rear wheel forward is arranged on a connecting position of the cross beam and the rear frame. The folding device is composed of a limiting block and a rotating part. The rotating part and a seat telescopic rod are fixed. The seat is fixed on a frame through the seat telescopic rod. The limiting block is provided with a rotating shaft hole and a limiting arc-shaped groove. The rotating part is provided with a rotating shaft hole and a fast-dismantled tightening screw installing hole. The separation distance between the rotating shaft hole and the limiting arc-shaped groove is equal to that between the rotating shaft hole and the fast-dismantled tightening screw installing hole. A fast-dismantled tightening screw is installed on the fast-dismantled tightening screw installing hole. The folding electric bike reduces occupied space greatly.

Description

Fold type folding Electrical Bicycle before a kind of trailing wheel

Technical field

The utility model relates to folding electric bicycle, is specifically related to the preceding fold type folding Electrical Bicycle of a kind of trailing wheel.

Background technology

Existing Electrical Bicycle majority is the open-close type folding mode, the width after folding more greatly, inadequately compact, folding and launch all inconvenient, carry difficulty.

The utility model content

The utility model provides fold type folding Electrical Bicycle before a kind of trailing wheel for addressing the above problem.

The utility model is realized by following scheme: fold type folding Electrical Bicycle before a kind of trailing wheel, comprise the car front-wheel, rear wheel, handlebar, crossbeam, seat wraps and is used for fixing the back vehicle frame of rear wheel, be provided with rechargeable battery in the described crossbeam, this rechargeable battery connects controller, described controller connects the rear wheel hub motors on the rear wheel, described crossbeam is provided with the folding device that will roll over before the trailing wheel with vehicle frame place, back, this folding device is made up of limiting stopper and revolving part, revolving part fixes with seat bag expansion link, the seat bag is fixed on the vehicle frame by seat bag expansion link, limiting stopper is provided with rotation axis hole and spacing deep-slotted chip breaker, revolving part is provided with shaft hole and quick detach bottle rigging screw mounting hole, the spacing of rotation axis hole and spacing deep-slotted chip breaker equals the spacing of shaft hole and quick detach bottle rigging screw mounting hole, on the quick detach bottle rigging screw mounting hole quick detach bottle rigging screw is housed.

The utility model folding electric bicycle has significantly reduced and taken up room, and not only can fold, and can also stretch, and is easy to carry, launch and folding convenient freely, can put into boot when going on a tour, can also prevent stolen.
