Taking the lane is very good, particularly in situations where dooring or roadside debris fields are threats.
Kevin, what sorts of tires are available for the Veloteq? You may be able to find some proper winter tires, or something that can be modified into such. In winter I can ride in just about any weather, over glaze ice even, thanks to these:
Making your own isn't unheard of, if you can't get them premade. All you need is a pair of tires with some knobs on them, the right length of sheet metal screws, and a tire liner to protect your tube. It would really help the winter riding.
On the lifespan of SLA batteries, its correct that using less power on each charge will increase the battery's lifespan. Being stubborn and draining it down to the last drop on the other hand, will also make it die a *lot* faster.
SLA batteries also benefit greatly from being recharged immediately after use, as they suffer from sulfination which is the main cause of them wearing out. Anyone doing this will also see a lifespan increase. There are also devices called desulfinators, which are normally used to rejuvenate forklift batteries but i've seen some successfully used with e-bike batteries. These devices work quite well at extending the life of an SLA battery.
