This is pretty much a standard Phat (brand) beach bike with an EZ Motorbike engine kit installed. Phat is out of business but other suitable bikes are available online.

Extras include: Sturmey-Archer front brake, Schwinn Panniers and speedometer, I found these at Wal-mart (where else) for $25.00 (2017 price). They are made of fairly lightweight material and very roomy. Not the best certainly, but if someone steals them, I won't be crying about it. The rack is made for an Electra bike. I liked the design so I made a bracket to fit my Phat See-breeze brand bike. The wheels are an upgrade, heavy duty with thicker spokes.

One of the coolest additions to this bike is a custom hub and sprocket made by the Manic Mechanic, now out of business. The hub was certainly a precision fit and worked wonderfully and was reasonably priced.

I installed a wider set of crank arms and an inexpensive set of pedal extenders which spaced the pedals out for a more comfortable peddling position. What is left of the original bike is the frame, seat and handlebars. Everything else has been upgraded.

Bell impulse Led Light. I like this light because it has a flashing mode that I use all the time. I would like to get some yellow or amber material to make the light more distinctive.

I made sure that the chain on the motor side did not need a tensioner. I installed a slotted tang and put a sprocket from an old derailleur as suggested by: Motorbike Mike. It's clean and simple.

I used some square tubing to make a stand for when changing a flat tire. I welded a receiver on the bottom of the frame.

I zip-tied the battery pack for the light as shown. The case was from an old-style wildland firefighter's headlamp.

Here you can see that the clutch case has been modified. Up to now, the bearing shaft really had no support at both ends. This was the fix.

The black thing is designed to support the end of the bearing. I spaced it out with square tubing. I also notched out the bottom of the frame and added a pulley to help the clutch activate more smoothly.

Here is the actual bearing that needed support.

Here is a slightly different angle to the clamp which fastened the sprocket to the hub.

Front view, I ended up being not real satisfied with the springer front end and ended up adapting a mountain bike front end to the bike including disk brakes. This worked a lot better.

Just another un-cluttered view of the bike.

In this photo you can see the slack in the pedal chain that would be eventually modified with the re-used old derailleur part.

Just for fun, here is the Shandong motor's parts breakdown.

Riding Impressions - The motor starts most of the time with one pull. There is a noticeable "flat spot' when accelerating. This is probably due to too lean a jet (California emissions.) It is not a huge problem but one that I would eventually like to fix, (I never did). With the present gearing, the bike is easily off the line with a couple of turns of the pedal. The cruising speed is smooth at about 25 mph. Top speed on a flat surface is 31 mph. It would be nice to be able to do 35, but the lower end would suffer with higher gearing. With an honest 25 mph, I can keep up with the traffic going through the wonderfully timed lights in downtown.

Impressions Cont:The drive (clutch) unit is very simple but I ended up making a couple of modifications which reduced the slippage I noticed. One was an improvement to how the clutch cable attaches to the arm, the improvement made it so the cable doesn't get squashed and if necessary, the cable is easily removed or replaced.

Specifications: Engine- 4 stroke: Shandong Hashing 49.4 cc - Weight: 76 lbs - Gearing: Front Sprocket = 10 teeth, Rear = 56 teeth. - Comfortable cruise speed: 25 mph. - Top speed: 31 mph (flat and level) Tested Miles Per Gallon: 170.4 @ 22 mph (pretty amazing)
