| How to pick the right bike for your Golden
Eagle |
Because bicycle manufacturers are as bad
as auto industry for making minute changes
from one season to the next, suitability
cannot be Guaranteed - you will need to check to be sure our unit would fit the bike.
Our Drive Rings fit either
32 spoke or 36
spoke wheels (Recommended),
requires the
Standard 3 cross or 4 cross
spoke pattern,
common to most bicycles.
Fits 24", 26"
and 700c(Not recommended)
wheels.
To provide the most dependable ride and simplify
installation and least expense, we recommend:
26" - 36 spoke wheels (stainless steel,
straight spokes preferred), dual Rim brakes,
Solid axle w/nuts on the rear wheel and a
bike that is comfortable. The shorter spokes
on a 24" wheel are stronger than larger
wheels (4x spoke pattern is perfect drive
ring fit), the smaller wheel lends more low-end
torque. A 26" wheel allows faster top
end speeds and is less expensive for tires
(more common).
Measure to know if you have the room for our drive
ring, between the rear forks. Minimum clearance
is 3 3/8" between rear forks/seat stays,
when measured 8 1/2" up fork from axle.
The long edge of a credit card is 3 3/8",
if the card fits between forks, at 8 1/2"
from top of axle, you have clearance. Check
both upper and lower forks.
A Solid axle with Nuts is required to securely
mount the engine to the bikes' frame. If
your bike has the 'quick release' feature
on the rear wheel, you will need to have
it replaced - recommend replacement with
our 10mm Quick Release(QR) replacement axles
(hardened and magnetized) that fit the cones
and bearings of the QR axle you're replacing.
Wheels and axles are on the Accessories side of order page.
If your wheel has a 'slip-off' cassette (gear
cluster on rear axle), you'd install the
cassette and any spacers onto the Velocity
wheel. If cassette isn't 'slip-off' and it's
necessary to purchase one from a bike shop,
$15.00 - $20.00 range is all you'd want/need.
Fits 7; 8 and 9 speed cassettes - 7 speed
cassettes require one spacer.
Some find the best, most
dependable and least
expense using the bike
they have and getting
one of our wheels. Fenders,
lights, rear
view mirror & speedometer
are nice additions.
We enjoy 26 x 1.95 tires
on most of our bikes,
if you want a little more
cushion between
rim and road, we'd recommend
26 x 2.125.
If building for transportation, you require
the most dependable - we recommend our wheels,
especially made for motorizing. Bicycle wheels
aren't designed to pound the road at speeds
of 30mph constantly, our customers have exceeded
30,000 miles - you Need a strong wheel, a strong bike (not the hi-end
lightweight jobs) and calluses!

*** Front Wheel Install
for Trikes: (Please specify Front wheel mount when ordering). Requires several modifications to a stock
order.
- Engine would be installed on an engine bracket,
turning engine 10 degrees, to allow easier
access when fueling the engine's gas tank
- no additional charge.
- We would drill and tap a bolt hole on the
back of the bracket, for attachment of front
mount strap - no additional charge. When
mounted on rear wheel, front strap is only
to prevent engine from rolling off the back
wheel - front wheel installation, strap would
stabilize engine, holding mount securely
to prevent engine pushing against front forks.
- $10.00 charge to shorten throttle cable approximately
2 feet - a lot of extra cable could easily
become snagged; wrapping excess cable up
to prevent it being snagged on something,
would remove all throttle free play, engine
would constantly over-rev.
*** Disc brakes (Not recommended):
- Disk brakes are expensive to maintenance
and, because of how they work, put a lot
of stress on the spokes w/o motorizing. Braking
stress combined with pedaling or engine torque,
puts stress on spokes going and coming. We
believe we have overcome this problem with
the Velocity wheel on the Accessories side
of the order page: 36 - 105 gauge stainless
spokes with Disk brake hub, 10mm axle has
4 sealed bearings.
- Some disc brakes sit within bike frame, only
requiring a washer or nut to space lower
strap out, for clearance. Some find the need
to grind or file an 1/8" sliver (crescent)
from lower strap for brake clearance, others
protrude so far beyond the frame of the bike
that installation becomes tedious, if not
impossible. If possible, we recommend you
steer clear of disc brakes.
To check to see if the
disk brake would obstruct
clearance of Lower Mount
Strap - a yardstick
is helpful (or something
similar).
Place yard stick on top of axle - pivot toward
seat then back toward rear of wheel - does
any part of the disk brake protrude so far
beyond bike frame that it would interfere
with the lower strap?
We encourage engine placement as close to
the seat as possible for better balance. Installation details may be helpful as well, see Fig E (halfway
down the page).
*** Internal Hub gears (Not recommended)
The larger hubs throw spoke
alignment off,
spokes do not align with
spoke slots of Drive
Ring. Internal gears are
nice for easy pedaling
but not required when motorizing.
tiny little
gears don't hold up well
to motorized speeds,
frail and expensive to
maintenance.
