How to pick the right bike for your Golden Eagle

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, and 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 wheels – we recommend ours, 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 the 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; they are frail and expensive to maintenance.
