## Description

The Handle Bob is a short 7/8" (22mm) diameter tube stub that attaches at 90 degrees to your existing handlebars with a pair of cable ties. This provides a convenient way of attaching thumb lever throttles, CA Aux Input controls, and buttons/switches to your bike without needing to slide off your existing grips. It also lets you attach these devices to curved drop bars or recumbent bikes and trikes with unusual bar geometry. Made from black anodized aluminum, sold as a pair, includes cable ties.

Review: Sturdy and easy to mount - These or a product like thisbhas been around for many years in the recumbent world, way befor ebikess. They are great to mount a light on the front post of a tadpole trike (bicycle) and that was my reason to purchase. Sturdy and easy to mount. I do believe they are slightly overpriced however and the company should off the sale of one, not force you to buy two. Honestly, you could make one out of any pipe and a dremel butbit wouldnt be Cnc'd and perfect like these. You gotta put some rubber between your bar and this to help it not slip
Review: Very useful - A must have for dropbar e-bikes.
