Well because of Forbes post, I just picked up a Charger LX model
today from electroportal. Sam, the owner, is a great guy and we
talked and test rode bikes for 3 hours.
I put the bike together in a casual 2.5 hours. It would have been 2
hours if I stopped to read the directions for the front brakes which
took me the longest to adjust. But that's just the way I am. :?)
I didn't get much chance to ride around yet, just around the block.
It's a true pedal assist bike because you have to pedal it for the
motor to kick in. It'll give me exercise but I can get to work
faster too. In fact, I can use it more for short errands and such
instead of getting in my car now.
The Shimano Nexus gear and break system is something that I've never
seen before. Really intriguing how it works and I'm going to try to
learn about it more. It's cool that you can be at a stop and change
gears without pedaling.
The electric assist is great. I found an EV grin on my face zipping
along at a decent speed with just a bit of power from my legs. The
battery management and charger are integrated into the removable
battery pack. Well thought out. The battery management prevents
the user from discharging the battery to dangerously low levels that
would damage the pack. The speed sensor stops motor assist if you
go over 20mph. Legal thing. I don't understand why we limit
electric bicycles speed but cars can go 140+ mph (well my car can :)
I think I could use some higher gears so that I can go faster. But
we'll see after several more runs. I think the gearing for the
pedals was decided on so that it could not go much faster than
20mph. I'm in good shape and had to pedal pretty quickly to get the
motor to kick out. It's difficult to go faster than 20mph because
when the motor kicks out you loose lots of power from the motor and
you feel the bog in your legs which makes you slow down. And then
you are in a cycle of boost, no boost, boost no boost. And I decide
to settle my peddaling down just below the cut off point even though
I want to go a bit faster...maybe 25mph or so.
I'm going to adjust the speed sensor to trick it that I'm going
slower than it thinks like this guy did on his charger bike.
He's now able to go 22-28mph which should be satisfactory to me.
Technically illegal...but so are the people that are breaking the
automotive speed limit every day and the modified gas powered
scooters that zip along at close to 30mph making noise like an angry
And the price couldn't be more competitive. Other e-bikes I was
looking at such as the motobob or the slipstream would have cost
about the same except that I would have had to provide the bike
which would have been a couple hundred dollars alone. An amazing,
