Car Replacement

It’s no secret that we are passionate about cycling, and particularly commuting via bicycle. A bicycle is the perfect car replacement. You’re not only exercising for free, you’re actually saving a significant amount of money compared to commuting via car. So, let’s make a quick checklist of all the things biking to work does for you that a car does not:

  • Fun ✔
  • Exercise ✔
  • Save money ✔
  • Spend time outdoors ✔
  • See more of your city ✔
  • Better for the environment ✔
  • Less stress ✔
  • Save time ✔ (1 hour commute covers exercise and travel vs 40 minute car commute and hour at the gym to get the equivalent amount of exercise.)

Why Biking is Alabama Sucks

The only problem with this is that we live in a notoriously unbikeable state, and a potentially even more un-bike-friendly city. Everybody seems to love bullet lists, so I’m going to utilize another one to help paint you a picture using numbers:

  • Huntsville has a terrible problem with sprawl, encompassing 214 square miles with 180k people, and the city is still annexing in more area. Comparatively, Atlanta manages to fit 490k people in 134 square miles. Because of the sprawl, all commutes are inherently longer to get to work, bicycles included.12-x18-m18-bicycle-routetraffic-signs-767
  • To top off the sprawl problem, Huntsville has less than 30 miles of “Signed Bike Routes”, we aren’t talking bike lanes…we are talking a tiny ass sign with a silhouette of a bike on it. (Pictured here)
  • According to the National Highway Administration, Alabama is ranked #49 out of 50 for most fatalities of bike commuters.
  • 0.1% of people in Alabama are commuting via bicycle, which puts Alabama at #48 out of 50.

With these numbers, its no wonder that Alabama is the 3rd fattest state in the country, has the highest percentage of diabetes, the highest number of infant mortality rates, and ranks 49th in life expectancy. The sad truth is you’re more likely to live longer if you live in Bosnia, Uruguay, Mexico, Vietnam, Iran, Nicaragua, the Dominican Republic, or Libya than you are if you live in Alabama. There is a culture of fear and disdain of anything healthy.

Who Gives a Shit

None of the scary items from above stop us from biking, though. Rejecting the norm is not only fun for me, but almost necessary. Also, improving the biking culture and participation in the area is hard to do while sitting on the sidelines. The real catalyst for building the perfect commuting bicycle came from our well storied move into our house-hack.

My commute to work more than doubled (which went from 5 to right at 11 miles one way, still impressive by most American’s standards), but the real kicker is that it went down some much busier roads. My previous commute was only 5 miles down a single three lane road, that had a turning lane the entire length of it so people could easily go around me, it also went through three school zones, so people were forced to slow down periodically. The new commute is almost exclusively 4 lane roads that have higher speed limits, more cars, less traffic lights, and no school zones to remind the assholes that they’re not in a NASCAR race.

Enter the E-Bike

If you’re unsure of what that is, it stands for “electric bike”. If you still can’t manage to reason your way through that one, how have you made it this far in life? Imagine a bicycle, and now imagine a motor on that bicycle powered by batteries. That’s pretty much the gist of an e-bike. The motor is what makes it a true car replacement in most scenarios.

Types of E-Bikes

There are generally only a couple types of E-bikes I was considering since this was going to be a DIY project and not buying a purpose built e-bike off the shelf. DIY E-bikes are cheaper, faster, potentially more durable, and endlessly customizable. My options were: hub drive motors, and mid drive motors.

Hub Drive

The hub drive puts the motor inside the wheel hub of your bicycle. I’m no mathmatician, but there are two wheels on bikes. This means they have two options for hub motors, either the front or rear wheel. They are easier to install however, the drawbacks of the hub motor are that they affect the weight distribution of the bike, it can be harder to perform routine things like a tire change, and because they aren’t geared, they tend to go slower than mid-drive motors.


Mid-drive motors are installed where the pedals are. Because it’s a pedal assist, you can maintain the rear gears on your bike giving you more versatility on speed and range. Mid-drive motors are typically better balanced, easier to perform maintenance, and faster. However, they are harder to install, by a few hours. They are larger, which cuts into ground clearance. Also, the additional power and speed means they typically go through drive-train parts faster (chain, sprockets, etc).

Picking a Bike

Based on my research, and weighing the benefits and drawbacks to both, I decided on a mid-drive kit. A mountain bike is the ideal choice for a mid-drive kit because of the weight, durability, and speeds you reach on an e-bike. A full suspension can be comfortable, but inefficient when it comes to pedaling. This is because a large amount of energy is wasted bouncing the bike up and down. Also, they typically have less space in the frame for a battery pack, or water bottles. A front suspension (aka hardtail) will absorb the impact from potholes, rough terrain, or even hopping curbs which assists in preventing flat tires, but also have an empty space in the frame to fit pretty much any size battery pack. A rigid frame bike has less maintenance than suspension bikes, but the ride is rougher, and flats are more common, especially at the high speeds of an e-bike. So, the best of both worlds in my opinion is the hardtail.

Buy Used

After a while of periodically searching Facebook Marketplace and Craigslist, I came across the perfect bike for my project, a Diamondback Sorrento. Front suspension, in good shape, and I bargained the guy down to $100. I went ahead and bought some street tires (Schwalbe Marathon Plus have great tread, and an extra layer of protection for preventing punctures), a thorn resistant tire liner (again to prevent flats), new chain, and upgraded brakes (with the added speed, you definitely want to stop quicker) all for around $75.

The Car Replacement Kit

Now it was time to fit the kit. I went with a kit from Luna Cycle that they had on a special anniversary sale back in November, so if you are interested in saving a decent chunk of change, you can just hold out a couple months. They have a few options for the motor, but I went with the BBS02 because it was cheaper, and lighter. The BBSHD is a little more powerful, but also a little heavier, and about $225 more expensive. The kit came with everything I needed (motor, battery pack, display, speed sensor, basic charger) and the best part is it was all plug and play. Once I got started on it, it only took me a couple of hours to install. I also went ahead and upgraded to the fancy charger so I could try to protect my investment and make my batteries last as long as possible. The typical price of the kit I bought is $990, but because of the anniversary sale, I snagged it for $750.


Now, I know what you’re thinking, $750!?! I asked myself the same thing. Was it worth it? Will I use it more than my regular bike that already sees a bunch of use? Is it really that much better? Yes, yes, and yes.

The Fun Stuff

The controller and speeds can be customized, but I currently have it on a 5 level pedal assist system along with a throttle in case I need an extra oomph. I typically ride to work at level 2 or 3 and I consistently maintain a speed of around 25-30 mph with a moderate amount of effort. This is about 10 mph faster than my typical speed. With a slight descent, and a little more effort, I can hit speeds of 40 mph+ and that’s still only at level 3 of 5. So it’s a hell of a lot of fun.

With these speeds, I can keep up with traffic much better, which gives me peace of mind. Also, the range of assistance means I’ll go further on my e-bike than I would typically consider on my regular bike, so I’ll utilize it more often and forego taking one of our cars.

Kickin’ Ass and Taking Names

Comparatively speaking, the Sondors Thin (potentially the most popular e-bike in a similar style hardtail) off the shelf costs $1,135, has a top speed of 20 mph (lol), and shorter range. It’s important to mention that while you may expect the bike to take significantly longer, my car commute takes me 20 minutes, while the commute on my handy dandy e-bike only takes me 10 minutes longer.

According to AAA the average cost per mile for a vehicle is up to 60.8¢ per mile, compared to the 1.5¢ per mile that my bike is costing me, leaving me with a net savings of 59.3¢ per mile. With a 22 mile total commute, I’ll have to ride my bike to work 71 times (which I will gladly do) for my e-bike to pay for itself purely on the cost per mile, and not considering the increase in happiness, decrease in stress, decrease in healthcare costs, etc. If I commute to work 3x a week for a year, I’m saving $2k and that’s if I only rode to work, and didn’t ride any other trips. For a little over $900, and an afternoon of getting my hands dirty with the kit install, I have a viable alternative to the car that will quickly pay for itself and put a much bigger smile on my face than riding in my car could ever do. In my book, that is money well spent.

    I look at e-bikes as having three component benefits. One is cost savings. 2 is environmental, social, Etc benefits. 3 is plain fun. If you look at it that way, then you don’t have to justify the pay back. Nearly as much since cost is only one third of the benefit. I love ebikes, and it sounds like you built yourself a very cool one. They have a great application for so many people, too. The main two benefits that I see are they allow you to ride up hills with similar effort to riding on a slight downhill because the motor does most of the work. Also, the sweat Factor virtually disappears, as I have been able to ride a 17 mile one-way commute to work and back in class is and a golf shirt without sweating. And I’m a sweater!
    I recently watched a YouTube video where the Ted Talks speaker explained why ebikes have an effective efficiency of 800 mpg, if you want to express their efficiency in the form of car mileage per gallon for an apples-to-apples comparison.

    • James Lowery

      I’ll have to find that Ted talk, because that sounds right up my alley. 800 mpg is astronomical! That’s an interesting way to weigh out the cost/fun/environmental equation, I’ll have to start doing that so I won’t beat myself up over price as much.

  • Captain DIY

    I have really been thinking hard about this for a while. My commute is 14 miles, but I could ride a dedicated bike path almost the entire way. I’m thinking of trying it out by driving halfway, where there is a parking area right by the bike path, and then biking the rest of the way. I think I’ll do that a few times and try it out before I invest in an e-bike. But man, they’re so cool!

    • Dustin Branham

      It’s a great idea, Captain DIY. Having a dedicated bike path nearly the entire commute is something most of us can only dream about. You might also try riding a couple days per week and driving the others. You’ll find that a 28 mile round trip commute will cause the miles to really add up, and even for fit people that will leave you tired. So maybe start with 1 day, then 2, then work up to as many as you’re comfortable doing. The great thing is that you’ll get you entire week’s exercise quota just by going to work!

    • James Lowery

      I would echo what Dustin said, working your way up is better than diving in head first and fizzling out quickly because it’s difficult. Driving 1/2 way is another way around that, which can make the distance and time much more manageable and you can work your way up to the full distance over time. Another benefit I’ve seen while using a the protected bike lane is that you don’t have to bust your ass as hard on your ride. Unfortunately, if I’m on the bike, I’m typically pedaling as fast and as hard as I can regardless of whether or not I’m on a trail, if I’m on my regular bike or e-bike, or how much assistance the motor is giving me on the e-bike.

    “you’re more likely to live longer if you live in Bosnia, Uruguay, Mexico, Vietnam, Iran, Nicaragua, the Dominican Republic, or Libya than you are if you live in Alabama.” Good god, that’s true? How incredibly depressing…

    • James Lowery

      Unfortunately, that wasn’t bloated rhetoric, that was 100% true based on average life expectancy. It’s a sad thought that developing countries can keep you alive and healthier longer than a state in one of, if not the most, advanced country in the world.

    “Rejecting the norm is not only fun for me, but almost necessary”
    I have never felt like more of a badass than when I biked home in the rain in 35 degree weather. Fuck norms. Normal is boring. Whoever wants to be normal?
