On our recent e-bike journey across America, we relied on a pair of Ergotec M-99 bicycle rearview mirrors. The mirrors have a diameter of 121 x 78 - 66 mm and an aspherical mirror surface which gives a large viewing area and reduces blind spots.

The M99 mirrors on the cross-country e-bike were an important safety feature.
Individual positioning of the mirror head is possible thanks to the ball joint with a 360° rotation.
The mirror with forged aluminum housing and a short mirror arm of 130 mm can be mounted left and right on the handlebar.
An E-bike-Safe Mirror
Due to the European e-approval number, the M99 mirror may be fitted to e-bikes up to 45 km/h / 28 Mph and motorcycles.

Exceptional Stability
The mirror is expertly crafted and composed entirely of aluminum, giving it exceptional stability. The hinge is notably sturdy and requires a significant amount of force to adjust, which is a positive attribute as it ensures the mirror remains adequately aligned, even when jostled
PLEASE NOTE: An adapter for clamping in the handlebar is optionally available and required to install the mirror. You will need to buy both.
Look for the Ergotec Adapter für Spiegel M88/M99 available on Amazon. The M99 mirror is unavailable on Amazon in the US and is out of stock at Amazon UK. We bought four mirrors from www.bicyclehero.com/us/ with free shipping. They also have plugs for the mirror.
The Ergotec M88
Ergotec also produces the M88 rearview mirror available on Amazon, which is smaller. We e-biked across America with the larger M99 mirror.
Exceptional Reflection
The mirror's reflection is exceptionally clear and provides a broad view of the surroundings, surpassing that of a flat mirror. Although it may be pricey, the mirror's reflection quality justifies its cost. It is skillfully designed and expertly crafted, making it a wise investment.
