Re: Would you charge a 4s LiFePo with a "15V" wall wart (intended for charging a 12V SLA)?

yes
I would but with some kind of reliable LVC.
Since such "wallwart" doesnt have any CC/CV charging profile it might be hard on LiFePo cells.

Ride in our city a lot during winter.

Do you ride on just regular MTB tires?

Any bicycle seat of decent quality would have markings on rails showing how much back or forward you can slide seat.

Re: Cheapest e-components for 55mph?

stopping power must be proportional to speed.
Regular bicycle brakes including disc brakes simply are not design to stop you safely from 45mph , leave alone 55mph which is crazy fast.
I echo previous poster , you better have good insurance.

Re: Inclement weather and e-bikes

my general rule for riding in winter is to ride away from cars as far away as possible, the reason?
salty mist cars trail behind which I definitely do not want .
unless they dont salt roads in your area.

Re: Inclement weather and e-bikes

so devil is in details as usual if it comes to winter riding, components wiring, connectors must be quality, no cheap.
I cannot imagine stopping in the middle of nowhere to push back shoddy connectors.

Re: What will it take to make ebikes, More mainstream ?

markz you see that is people mentality, popularity of ebikes would mean more demand for charging everywhere which for sure would result in busineses flipping breakers OFF on those outside plug ins. Now Calgary is EV ebike heaven if it comes to free charging all over the place example Home Depot , Ro...

Re: How do you preserve charger leads

I forgot to pack chargers before trip couple of times.
On my three 3 ebikes with chargers installed I never had any problems due to vibrations.
The thing is HOW are they installed on the bike.
mine dont rattle around when I ride.

dont know what your point is?
regular bicycle cannot cause accident on the road?
Of course reg bicycle rider can still hit pedestrian and injure him, right?
