Assessing an EUCs potential for a crash along a route

[Bob Eisenman]

Assessing an EUCs potential for a crash along a route:

For some EUCs the advertised safe riding surface is one without (about) one inch bumps or ruts. Riding within this tolerance is generally safe for riders. Wheel diameter, motor torque, rider weight and degree of incline all add into the consideration of what is considered safe.

If you place this requirement for safe riding upon the terrain a rider chooses to actually ride the EUC does the rider find:

1- 'no issues with safety'
 (newly constructed smooth sidewalk or other uniformly smooth riding surface) 

2- 'some safetey related issues'
 Constant visual surveying of the upcoming terrain is required to evaluate bumps, ruts or riding surface mismatches.

3- 'very complex safety issues'
Constant visual scanning, bump and rut riding skills and/or evasive bumb and rut riding maneuvers required.

4- 'increased day vs night safety issues'
When comparing day vs night riding along certain 'routes' the rider routinely faces the risk of crashing due to route illumination issues

5- 'wear full hockey padding and helmet'

A powerful headlamp (i.e., a lamp strapped to your head) is essential. You need a bright field of illumination in front, which may or may not be satisfactorily supplied by a built-in headlight on the EUC. But you need a beam with more distance and the ability to shine in different directions other than the direction of travel. And having it on your head gives you hands-free control.

Two headlamps I use regularly and am very satisfied with are:

(The first one, Sahara Sailor, is dual purpose. It can be mounted on a handlebar or on a head strap.)

A spec sheet (found on the net) lists 3cm as the maximum 'staircase' for the Ninebot S2 model (ie. about the distance from the wheel rim to the bottom of the tire tread).

The rider should always be scanning ahead, even on the smoothest of routes. You never know when a small branch, banana peel, et cetera could foil the plan!

In fact, is says smaller than 3cm. This spec is definitely on the safe side when it comes to complaints.
