13729Re: recovering from accident, seeking advice
- Oct 15, 2011The Kona Ute has a considerably shorter wheelbase than the Big Dummy or a Xtracycle conversion bike. This will likely decrease loaded stability in my experience. However the OPs motor and battery could decrease the BD stability too depending on location and weight.
As much as possible keep the weight ahead of the rear wheel axle for best stability.
