Many people discover that lowering the seat height (which lowers their center of gravity) increases stability so they are safer at higher speeds.
Recumbent trikes (right picture) also offer more comfort with a wider, softer seat and a backrest. As a result, recumbent trikes are gaining popularity.
Worksman PAV-3 is a step in the right direction, a wide variety of recumbent and semi-recumbent trikes are available.
(Click here for even more variety.)
Few electric recumbents are available as complete trikes. So, you will likely need to get a kit and install it onto the trike of your choice.
For example, the Electro Cycle E-4 drive kit, designed to fit Sun Bicycles EZ-3 and X3,
may be adaptable to other recumbent trikes.
Although stable when stopped or when ridden straight ahead, standard upright adult tricycles
tend to tip when turning at "high" speeds. To avoid that
tipping, electric trike speeds are usually limited to about half of
e-bike speeds. If you want more stability, check the
or Easy Racers' EZ-3.
Recumbent trikes with two wheels in front may also be an
If you already own a trike that you want to electrify, consider these kits:
The comfortable and stable EZ-3
from Easy Racers is an excellent choice for transportation. The
recumbent design reduces wind resistance and greatly increases
comfort and safety over a standard upright trike. Like most
recumbents, the EZ-3 is safer in two important ways: 1) sitting
closer to the ground means that falls to the side hurt a lot less and
2) in a head-on collision, your feet in front prevents a head-first
fall over the handle bars. It's long frame also allows for
additional batteries for longer range.
One approach is to find and fit a
drive system. A hub motor seems like a natural fit, but
that 16" wheel is challenging. Here are a couple of options:
Bike Factory offers a kit that can be mounted to the front
wheel. Although they offer a slower speed kit for
tricycles, an EZ-3 is safe at the 15 mph speed of their
regular/two-wheel model. Also, ask about their two-motor
model. The friction drive may be a bit iffy on wet surfaces,
but the power is solid.
The Electro Cycle E-4 kit offers through-the-gears
drive which provides both good hill climbing and top-end speed.
Electro Cycle E-4 Kit
for EZ-3 Recumbent Cycles
Combine an EZ-3 recumbent trike
with a 500-watt drive system to get an extraordinary electric
trike. The lowered seat and feet-ahead design of these trikes
provide a comfortable, stable and safe ride. The Electro Cycle
E-4 takes advantage of the bike's gearing to deliver great
hill-climbing ability along with higher speeds - not just one or the
other like most electric bikes and hub motor kits. Most electric drive systems
directly drive a wheel. The E-4 mid-drive motor system works in
tandem with the rider's pedaling through the 8-speed rear derailleur,
significantly increasing motor and battery efficiency for higher
assisted speeds and better pulling power. The power-on-demand
drive system means no pedaling is required, but your effort will
extend the range and increase the acceleration and top speed. The stock E-4 battery
pack can be fully re-charged in about 4 hours with the included charger.
This comfortable and streamlined
recumbent from Easy Racers is excellent for transportation. The
recumbent design reduces wind resistance and greatly increases
comfort and safety over a standard upright trike. Recumbents
are safer in two important ways: 1) sitting closer to the ground
means that falls to the side hurt much less and 2) in a
head-on collision, your feet in front provide shock absorption and
prevent the head-first fall over the handle bars common in such
collisions. It's long frame also allows for additional
batteries, if needed, for longer range.
The similar two-wheeled EZ-1
is the most popular recumbent on the market, largely due to its
excellent reputation and low price. The three-wheeled EZ-3
provides the same great features with a stable, no-balancing-required configuration.
- 24-volt High Output Battery Pack
- 18 MPH Cruising Speed (without pedaling, faster with pedaling)
- Unassisted range up to 10 miles with the standard battery pack
- Quick Acceleration
- Amazing Hill-Climbing ability
- Weight: motor and gearing = 7 lbs.; battery pack = 20 lbs.
- Warranty: motor drive system = 6 months; batteries = 90 days

At last an Electric Bicycle that
is affordable. If you already have a bike or tricycle, the new Electric
Bike kits come with instructions for EASY assembly
for the do-it-yourselfer or can be installed by any bicycle shop. The
Electric Bike Kit is made right here in the U.S.A. With all
U.S.A. made parts. The kits are available direct from the Electric
Bike Factory in Florida. The new Electric Bike is made with a battery
that will provide constant power to the motor at top speed of 15 MPH
for two wheel bikes, 10 MPH for the tricycle. We also sell
bikes with the kit already installed.
manufacture electric motor kits for bikes, trikes and joyrider.
Our motor is not an exchange for ZAP's DX kits. We designed
our own kit. It is a friction drive. We have a front wheel and
rear wheel model. It is a simple one bolt bracket that mounts
our motor to a trike or bike frame. Our motor fits all trikes
and most bikes. We make 2 metal size rollers. The large
roller on bikes gives about 14-15 mph and on trikes 12-13 mph.
The small roller on trikes gives about 8-10 mph. We also make a
double motor (although in most cases it is not necessary) for trikes
that is one of the most powerful kits on the market. It is not
faster, but it is great for climbing hills or inclines. Our kit
is the easiest kit to install and Trailmate Co. is recommending us to

Bikes and Kits
Germany builds a variety of hub motors both in wattage rating and
gearing for both front and back wheels. Unlike many kits that perform
to specification only on 26" wheels, Heinzmann offers 16"-
and 20"-wheel kits. The quality and dependability of their
system is excellent. They sell a complete kit or individual
components. Their hub is used on the EV Global bike as well as
others. Their controller is a twist grip throttle that comes both in
a Pedelec, (must be pedaling) and an EBike version.
Light Electric Vehicle
Technologies provides service and warranty work on Heinzmann motors
sold in the U.S. To contact the National Service Center, e-mail Light

Heinzmann Motors is more than 100
years old. The company has been building electric motors for 40
years, and electric bicycle motors since 1994.
Here's a note from
someone who seems to know: "You are correct in that the
Heinzmann hubs with high torque have lower top speed. However,
Heinzmann is the best electric choice I know of for good torque. They
are being used on Pedicabs that haul up to 4 people around fairly
steep environments. You can select the gearing and voltage options
you wish from about 12 configurations now available from dealers in
North America. These include hubs with very high torque and ones that
achieve high top speeds as well as good compromise units."
