    I was gifted with a new in the box red Cranbrook frame. I've always liked the frame shape and steel construction of this bike, but never built a motorized one because of the weak components used throughout. I have a lot of really good components in hand to build it out as an electric 350 watt, which should not overly stress the frame while street riding. Just another simple build to add to my ebike education experience.

    Just pulled the Cranbrook out of the original box & the cable ties were still in place...box had never been opened. I have a really nice 1" Sunlite dual spring fork and a vintage style leather spring saddle that would look nice on the red Cranbrook e-bike so guess I'll go for the vintage cruiser look. Keep the one piece crank, but I've also got Schwinn repro bow tie pedals to replace the pitiful stock pedals. Leather wrap grips to match the butterscotch saddle leather & select a cool handle bar from my collection. Add a hub motor & battery....

    A red Cranbrook with a Sunlite springer is a pretty good foundation Rick. You are most definitely right about Huffy accessories. Beer can thick fenders and struts.

    Tom I doubt she will ride much, but it would be nice to take some rides together and she's a great rider and driver and has owned a lot of serious muscle cars and bikes during her life. Kinda' been thinking about snagging a small frame to build one for her & here's the opportunity, plus the color matches her car's finish quite close.

    The fenders & wheels/tires are the first things that will be upgraded. I'm pretty certain the rear hub motor is the way I'll go on this one. I'm concerned about using a hub motor on the toggle style suspension, quite a bit of un-sprung weight upfront on an old style springer.

    As I don't know nuthin about Ebikes, I am all ears. Will be fun to learn from your build.

    Tom I'm learning as I go primarily from others that are do it yourself advocates. Basic battery & controller guidelines and operation parameters with varying motor outputs is foundational material to build on. Charging guidelines for lithium based packs and safety guidelines for their safe & long term use, maintenance and storage is also vital information for all who are thinking about e-bikes.

    All that said manufacturers hype and other promotional material can be taken with a grain of salt & that chased with much research and some Jesuit logic. The basics of frame design with internal combustion engines or straight pedal power aren't changed by using a e-motor and battery pack drive. Balance, weight & center of gravity (physics) of the Newtonian variety aren't altered by the selected power source, other than by magnitude, i.e. 10 kw output is greater than 3 kw output regardless of using gas or battery power. So if you understand how gas bike frames and components work you've got a huge leg up on building an e-bike that will actually work.

    I'd say e-bikes built to high performance standards like Jeff and Pat build are gems...period! Unique style and high performance of hand built e-bikes or gas come at a premium which can be justified. Specialized downhill racer bikes also come at a premium that is understandable. However off the shelf bikes with 250 watt to 500 watt motors and good battery packs & controllers costing many thousands because they have mid drive, Kevlar belts, 3 speed hub, hidden in frame battery, lightweight frames etc. etc.; are mostly smoke and mirrors to charge more for 25 to 35 mph & 50 to 70 kilometers of range. Not good performance to value ratio in my economic world view, just brand name, slick tricks & buzzword hype.

    I do see the road legal,under $2,000. to $2,500. mass produced e-bikes having a legitimate place in the market....

    In the meantime I'm just sticking to the simple tried and true while picking up more information.

    Rick, you are a hoot! Jesuit logic i.e. Discernment.
    Now I understand your writing style perfectly and I am sure it has served you well. This forum is lucky to have your contributions.
    Do you know Joe Wong AKA Bakaneko on the other forum? Your and his quest run in parallel.

    Thanks Tom. I don't actually spend time over there, so I don't recognize the name or the nom de plum, other than it's a delicious fruit. I'm actually spending more time thinking and writing than doing and building bikes is just a small part of what I'm not really getting done. Yet I'm happy....and St. Augustine would, I believe, approve.

    Proven fact: not all great thinkers were Jesuits, and not all Jesuits were great thinkers, but all Jesuits know how to win an argument! By the way I'm not Catholic but love the devotion of the old brothers to both faith & logic These two things are not mutually exclusive by the way.
