Fossil Free Friday: $500 Simple DIY Electric Bike Formula (The non-sequitur apocrypha)


You're probably wondering why this post? This is the mop up of all the loose ends, or maybe just the proof that the Mesquite Hugger mind is indeed a messy desk.

Answering a few questions:

Why 36 volt/500 watt when we could've easily gone for 48V/1000 watt?
  • Well, first, we were shooting for low money, and 48 volt batteries are not cheap.
  • Second is the efficiency versus speed issue. 500 watts should let us travel around 20 mph for a much longer distance than 1000 watts at 25 mph (and I've met very few e-bikers who have tremendous restraint when it comes to a throttle or pedal assist.)
  • Also, the intended audience is beginning e-bikers who are focused on inexpensive transportation. Fast e-bikes create a lot of new problems - one of the biggest is the problem of speed perception. Car drivers do not expect to see a bike traveling at 30 mph, so they misjudge and cut you off. If you ride a bike at 30 on the street you will have close calls on a regular basis. (You better have great brakes and even better judgment.)

Why choose a cruiser?
Mostly because they are cheap, readily available, and often have just the layout needed for an entry-level e-bike. Also, you want a fat, heavy, laid-back bike for an old guy who is fat and laid back.

Why not a fat bike like the Sondors Original?
Quite simply, the the components are much more expensive and flats tend to be a bigger issue on them than on the more readily available sizes. (And they ride like a tractor.)

Just a bunch of random stuff I did not include in the other posts:



How to build a pretty killer mid-drive bike for less than $1000

Order this kit (while it's still on sale) and add it to a used mountain bike with really good brakes:


The Schwinn Blackwell dropped in price on Ebay


Can you build a decent-ish $350 e-bike?
Sure, but be prepared to sacrifice the LCD screen, pedal assist, and the advantages of a geared hub motor.


If I'm a glutton for punishment, which bike should I choose for my build?

Drool!

It's all about the jacksons! (Need fixing = run away!)

If I'm a Parrothead, what bike would you recommend?
It has a squawking parrot in place of a horn or bell!


What is the Mesquite Dream Build (this week)?
The cargo bike equivalent of the Karmic Koben S




What's your most fervent Mesquite Hugger wish?
That we'd stop fighting each other and fight climate change together.

May your messy desk inspire something better for others!
