I have a removable step made out of bar grating, that drops into a couple holes in the top of the bumper. Depending on how I'm set up, I can use it on the right or left. I only use it if it's the kind of job that will require me to get down out of the cab a lot, and towards the rear. If I forget to remove it (not yet) it's not any lower then my original step bumper and won't hurt the bumper if I caught it on something. Plus it'd be easy to repair.
BTW, I've used the little E bike several more times now, for real, on jobs. Besides being a practical mode of transportation, it's fun, so a welcome break from a stressful job like setting big trusses in high wind. I upgraded it to a 52 volt system, instead of the 36 volt that it came with, now it easily hits 35 MPH.
My favorite use, and one that makes me glad I took the time to make sure I could get it out and in the crane super quickly, is when I'm driving across town on the main drag. I can park the crane somewhere easy, get the bike out, and run some errands a few blocks away, and have more fun plus do it quicker then if I was making multiple stops and finding parking spots for the crane. No surprise, but the bike is way easier to get around busy parts of town then the crane! I get 6 mpg going down the highway with the crane, I hate to think what the mpg is in traffic. I recharge the bike for free with my home or crane shed solar system so i save money too.
