System Weight
Using SLA batteries, our largest system weighs about 70 lbs, the smallest
about 45 lbs. The chart below shows the weights of motor and battery. Add
another 8 lbs for the controller, wiring, bag, and rack/basket.
| Phoenix motor 23.5 lbs | RoadRunner & Sparrow motors 15.5 lbs |
| 36 volt 10AH appx 24 lbs (RoadRunner & Sparrow) | 48 volt 10 AH appx 32 lbs (RoadRunner & Sparrow) |
| 36 volt 12AH appx 30 lbs (Phoenix, optional for RoadRunner & Sparrow) | 48 volt 12AH appx 40 lbs (Phoenix, optional for RoadRunner & Sparrow) |
Compatibility with Bicycle Frames
Sparrow and RoadRunner motors have been used on all
sorts of front forks with and without suspension for years, and no one has
ever told us about a failure. Phoenix is another story entirely. Every
time someone puts a Phoenix motor on an aluminum front fork, the motor
tears the dropouts from the fork. The result is that the wheel takes off
without the bike, and you're left behind. Do not put a Phoenix motor on
aluminum front forks. Most manufacturers claim aluminum frames, but in fact the forks are
steel. Take a magnet off your refrigerator. If it "sticks" to
the fork, it's steel. Magnets are not attracted to aluminum.
Many have used rear Phoenix
motors on aluminum. We have not been told of any failures. Cromoly is said
to be stronger than steel, so it should work fine, and we have had no
reports of failures with Cromoly.
Front Suspension Forks
RoadRunner
and Sparrow are compatible with most suspension forks. The Phoenix motor is too
powerful for any stock production bicycle suspension fork available.
Choosing a Frame
We believe there are many, many good choices of
bicycles, and everyone can find more than one frame or style that is
comfortable and suits their needs well. The ability to offer choices was
one of the primary drivers behind our initial investment in hub
technologies in 2003. The approach we recommend is to visit your local
bike shops. Educate yourself on what is available, and speak to the people
about electric power systems. We caution that most bike shops still see
their primary customers as traditional pedal bicyclists who want a bike that weighs 10 ounces. If they don't like
the idea of electrifying one of their bikes, go to a different store. More
and more bike shops are selling our systems. They are finding a whole new
set of customers in the commuter market, and those who are embracing electric power are
growing.
Mixing water and electronics
We do not advise riding electric bikes on slippery
surfaces, especially commuter motors like Phoenix. They are too powerful
for any wet road conditions, and a wheel can easily spin out from under
you if you give it too much throttle. The controller is
not waterproof. When you buy a kit from ElectricRider, we pre-wire your
battery pack and place the controller inside the power bag
(pannier). Except in rare cases when ambient temperature is high and/or
you are running it hard, the controller should stay inside the bag for
protection. If you controller overheats, it may be necessary to move it to
the bungees on top of the bag. The motor is not waterproof, but water
would have to be forced into it, and whatever gets in should eventually
drain out the bottom. Repeated exposure to water over a long period of
time may rust the magnets. ElectricRider can refurbish motors in the rare
event that this happens to you. Cost is 1 hour labor + shipping.
Weak Links
When a system is designed, it's designed to work cooperatively with all the
parts in the assembly. The system could be thought of as a chain where all the
links need to be able to withstand whatever forces are required of them. There
is always a weakest link, whether it's a toaster, a car, or an electric power
system. ElectricRider tests extensively to assure the cooperative harmony is
achieved in the kits it offers. There is always a use we didn't think of, such
as pedicabs, three-wheeled cargo transports, and many others. When you build,
you need to think of how all the parts work together, and assure they can all
take the stress. The vast majority of problems people encounter relate to
weight. For instance, if you build a bicycle using a rear motor and extra-large
batteries, think about the forces you're putting on the wheel, and how that
affects the reliability of that wheel. It's a bicycle, after all, and putting
300 lbs on a wheel is just asking for problems. It is better to distribute the
weight by using a front motor or putting some of the batteries toward the front
of the bike. Simple solutions can almost always be found.
