Frame carrier - Battery carrier for attachment to the drinking bottle holder
This frame carrier is attached to the holder of the gear holder and is ideal as a carrier for the spare battery on longer trips with the pedelec or e-bike. The frame support attached to the support bracket fits perfectly into the frame - without disturbing the pedal. We have deliberately omitted side tabs or any limitation, since the two straps always keep luggage or battery in the middle and so different sized batteries or bottles, as well as other luggage can be easily transported. Matching straps or rubbers will soon be available as an extra. However, you can buy them cheap in the bike trade, Amazon or eBay. The battery sits with the right straps so tight that it does not move. He remains bombproof even after 50 km. You can theoretically lift the pedelec on the battery!
Another advantage of attachment to the down tube, which should not be underestimated, is the weight distribution on some wheels on the pedelec's seat tube. Especially pedelecs with front-wheel drive quickly lose traction and tend to accelerate to slipping or even spinning front wheels in the rain or on sand. This is very unpleasant, especially on slopes and unpaved roads. In curves, a front-wheel drive pedelec also reacts very sensitively. This is why there are often problems with rear-heavy operation. Falls are often attributed to the poor, rear-heavy weight distribution, especially when the pedelec is loaded with a lot of weight on the rear luggage rack. A spare battery on the down tube, attached to the intake for the bottle, can do wonders here. After all, so from 4 kg overweight on the axle of the rear wheel in the ratio about 10 kg extra weight that burden the front wheel. Consider that the leverage here is effective.
