MOTOR MOUNTING COMPONENTS AND HARDWARE

A MEGAPOWERED complete 2-stroke 66cc/80cc high performance MOTORIZED BIKE engine kit for converting your bike!

WHY RUNFAST IS THE HIGHEST QUALITY MOTORIZED BIKE ENGINE KIT IN THE WORLD

Heavier, stronger magnet rotor for more power!  Other cheap bike engines use weaker, less powerful magnet rotors.  Feel the difference!

Thicker, stronger, longer, stronger magneto cable wires for improved power transfer and better reach.

 

Heavier, thicker cylinder bodies and crank case  for strength and durability!

Heavy duty metal engine for added strength and durability

 

Wider front mount for better bike fitting accommodations of all bikes

 

Front and rear mounting studs are rugged thick 8mm.  Cheap low quality kits use thin, brittle studs that break off. 

High quality advanced u-bolt 8mm  universal motor mount plate 8.8 grade 8mm bolts and nuts for ultra hold and grip

 

High grade 8.8 standard for all bolting hardware.  The low quality cheap kits use 4.4 grade that strip threads easily. 

 

 

Balanced,  heavy duty quality crank assembly with smooth rides. 

Short crank rod for more power.  Cheaper low quality bicycle engines use lightweight poorly balanced assemblies with the longer rod with  less power  

 

Longer camshaft arms for easier disengagement

 

 

 

 

 

Superior woven throttle cable for super slick easy to twist throttle action.  Cheaper, lower quality engine kits have cables that bind up in the cable housing promoting excess wear/damage on throttle grip.

 

Higher quality, thicker bevel gear grease for superior lubrications

Recipes for disaster!
Format: Paperback
I wish I never paid for this. I wanted to support the author and purchase it, but I'm regretting it big time. The book is clearly written by someone with great technical abilities, and poor communication/teaching skills. It also lacks clarity, and repeats some concepts under different sections without explaining why or what you're gonna do with that information, as if some explanations were incomplete... all in a way that it is utterly confusing. Codes have lots of errors, so get ready to debug the heck out of them. I needed this for a project which aimed to make some processes more efficient, and now I'm stuck fixing a problem I did not need, increasing my workload. One of the worst cyber security books I've ever owned.

Really nice first book set for little hands
Format: Hardcover, Format: Hardcover
This is such a great little book set! The books are small, have sturdy hard pages, and are super easy for little hands to flip through. My baby is 11 months old, and these are honestly perfect for this stage, they’re simple, engaging, and just the right size for early learning. I really like that each book has its own theme (like wild animals, transport, shapes, etc.). It keeps things interesting and helps introduce new words in a fun and easy way. Another big plus for me is that the pictures are photo-realistic, which I think is really important when babies are learning about the world, they can actually connect what they see in the book to real life. The quality of the set is excellent, the images are bright, colorful, and crisp, and the books feel durable enough to handle lots of use (and chewing, let’s be honest). I also love the sturdy box it comes in, it keeps everything organized and makes cleanup easy. Overall, such a nice little library to read and enjoy with your baby. Definitely recommend!

Perfect Purchase
Format: Hardcover
Wonderful. Perfect size for little hands. Colorful. Caught my grandson’s attention as soon as my son unwrapped it. A good number of choices, so it’s easy to keep my grandson’s attention for over. 1/2 hour. I’d say that’s terrific for a little guy. All in all, this is the best set of books I’ve bought. Money well spent! He’ll probably wear them out before a little brother or sister comes along 😂

Perfect for first baby books.
Format: Hardcover
Loved these for my first daughter a few years ago and they definitely got their use. I wanted to make sure I got a new set for my newborn. They are perfect for learning all the basics with large pictures that help them associate with the labeled word. Easy to travel with boards books that baby’s can hold as they learn to grip items.
