The Roadster V2 is one of the most "stealth" ebikes on the market. Hiding all of the electronics was one of the primary design goals in making this sleek looking bicycle. In order to accomplish this a smaller compact display was used in place of our standard KD218 & KD21C. The one downside to this smaller display is that the clamp is more fragile than the others. In this article we go over best practices to keep your display working for years to come.
Tip 1: Location
Location on these displays is essential to keeping them damage free. The displays are shipped on the bikes with the unit up against the brake lever. This makes it great for accessibility, however the clamp is also on a bend and not fully supported. By moving the display inboard, it can be attached to a section of handlebar with no bend and better support. The display can also trade places with the brake lever, as that section is flat. The following pictures illustrates this.
Tip 2: Supporting the Display
The display clamp can last a very long time if properly supported when using it. Be sure to not press too hard on the display or bump it during use. The following picture shows how to support the display from behind to ensure minimal stress on the clamp.
Tip 3: Bolt Torque
The 2.5mm hex head bolt that holds the display on has a very low torque setting. It is often much less than people belive it to be. The bolt should not be tightened beyond .6nm. A good trick for the display, and with all controls, is to tighten them just enough so they do not wiggle on the handlebar. By tightening the display as little as possible it ensures that the clamp is not overstressed also, if it does get knocked or bumped, it will spin on the handlebar and not break off. Often times riders will tighten down their displays as much as possible, when those displays are impacted they have no other option than to break off where as a looser one would spin; and the rider could then reposition it like nothing ever happened.
