Converting a classic Schwinn Cruiser Bike into an electric bike is a tempting idea for many cycling enthusiasts. The thought of adding power to a comfortable, stylish cruiser for effortless rides around town or along the beach path is definitely appealing. But when you start looking into the options, the question quickly becomes: is it better to build your own e-bike from a Schwinn cruiser, or is it more practical and cost-effective to buy a pre-built electric cruiser bike? Let’s dive into the world of DIY e-bike conversions and pre-made e-bikes to help you decide what might be the best route for your Schwinn cruiser dreams.
The DIY E-bike Conversion Path: Hub Motors and Mid-Drives
For those who love a hands-on approach, converting a Schwinn cruiser into an e-bike yourself can be a rewarding project. There are generally two main types of e-bike conversion kits to consider: hub motor kits and mid-drive motor kits.
Hub Motor Kits: Simplicity and Affordability
Hub motor kits are often seen as the simpler and more budget-friendly option for DIY e-bike conversions. These kits typically involve replacing either the front or rear wheel of your Schwinn cruiser with a wheel that has an integrated electric motor.

As one cyclist noted, “Simple hub motor kits on amazon are around $150-$200 on amazon (possibly cheaper on ebay?).” This initial cost is certainly attractive. However, the simplicity can come with some trade-offs.
Challenges with Hub Motor Kits:
- Dropout Filing: Older Schwinn cruiser frames, like many traditional bikes, may have dropouts that aren’t wide enough to easily accommodate the axle of a hub motor. This might require filing down the dropouts, which can be a bit daunting for those without experience working with metal. This is especially true if you are using disc brakes, as alignment becomes even more critical.
- Torque Arms: Hub motors, particularly more powerful ones, can exert significant torque on the frame dropouts. Without proper reinforcement, this torque can damage the frame over time. Therefore, a torque arm is essential to secure the motor and distribute the force. This often involves some DIY fabrication or adaptation.
- Front vs. Rear Hub Motors: While front hub motors are easier to install as they don’t interfere with the bike’s drivetrain, they can sometimes affect steering and handling, especially on loose surfaces. Rear hub motors offer a more natural feel but can be more complex to install, particularly if your Schwinn cruiser has gears or coaster brakes.
Despite these challenges, many successful DIY e-bike conversions have been done with hub motors. Online communities like “endless-sphere” are great resources for tips, tricks, and troubleshooting if you choose this path. As the original forum post humorously suggests, be prepared to embrace “duct tape, cable clamps and zip ties” to get everything just right!
Mid-Drive Motor Kits: More Performance, More Complexity
Mid-drive motor kits offer a different approach to e-bike conversion. Instead of the motor being in the wheel hub, a mid-drive motor is installed in the bottom bracket area of the bike, where the pedals crank arms are located.

Mid-drive kits, like the TSDZ2 mentioned in the forum post, are generally more expensive than hub motor kits. The post notes, “In the end, the tsdz2 was about $450 plus about the same for a battery.”
Advantages of Mid-Drive Motors:
- Better Weight Distribution: Positioning the motor in the center of the bike results in better weight distribution compared to hub motors, which can make the bike feel more balanced and handle better.
- Utilizes Bike Gears: Mid-drive motors work with the bike’s existing gears, allowing the motor to operate more efficiently across a wider range of speeds and terrains. This can result in better hill-climbing ability and a more natural riding experience.
- Potentially Higher Performance: Mid-drive motors are often more powerful and efficient than hub motors, providing a more responsive and capable e-bike.
Disadvantages of Mid-Drive Motors:
- Increased Complexity and Cost: Installation of a mid-drive kit is generally more complex than a hub motor kit, often requiring more specialized tools and mechanical knowledge. As the forum post highlights, the initial cost of the kit and battery can quickly add up.
- Potential Noise and Reliability Issues: Some mid-drive motors, particularly older models, can be noisier than hub motors due to the gears within the motor. The forum post mentions experiencing “noisey(gear noise)” and later “clunks and click noises” with a TSDZ2 motor, along with axle play issues. Reliability can vary between different mid-drive motor brands and models.
The Cost Factor: DIY vs. Pre-built E-bikes
The original forum post raises a crucial point: “While it was a great experience, it wasnt cost effective for me.” While the allure of a DIY project is strong, it’s important to honestly assess the potential costs and compare them to buying a pre-built electric cruiser bike.
DIY E-bike Conversion Costs:
- Kit Cost: Hub motor kits can start relatively low, but quality mid-drive kits can be in the $400-$800 range or higher.
- Battery Cost: A good quality e-bike battery is a significant expense, often costing as much or more than the motor kit itself. The forum post mentions battery costs ranging from $500 to $500 for a replacement after an initial battery failure.
- Components and Tools: You may need to purchase additional components like torque arms, wiring, displays, and potentially specialized tools for installation.
- Time and Effort: Don’t forget to factor in the time and effort required for research, installation, and troubleshooting. Your time has value too!
Pre-built Electric Cruiser Bike Costs:
Pre-built electric cruiser bikes offer the convenience of a ready-to-ride e-bike without the hassle of DIY conversion. While the upfront cost is generally higher than a basic DIY kit, it can be comparable to or even less than a high-quality DIY conversion when all costs are considered.
[Imagine a photo of a stylish pre-built electric Schwinn cruiser bike. Alt text: A brand new Schwinn electric cruiser bike, ready for relaxed rides.]
The forum post mentions test riding an “iZip Moda e3 a week or so ago (Brose motor, 28mph speed pedelec, $2250) and have since ordered one.” While $2250 is a significant investment, it buys a complete, warrantied e-bike with a reputable motor system.
Factors to Consider When Comparing Costs:
- Motor and Battery Quality: Pre-built e-bikes often use established motor and battery brands with warranties and known performance. DIY kits can vary widely in quality, and you may need to do more research to ensure you are getting reliable components.
- Bike Components: Pre-built e-bikes are designed as complete systems, with components chosen to work well with the electric assist. When converting a Schwinn cruiser, you are working with the existing bike components, which may or may not be ideal for e-bike use.
- Warranty and Support: Pre-built e-bikes come with manufacturer warranties and dealer support. With DIY conversions, you are largely on your own for troubleshooting and repairs.
Bafang Ultra and High-Performance E-bike Dreams
The forum post concludes with “Bafang Ultra compatible frames would be AWESOME.” The Bafang Ultra motor is a high-performance mid-drive motor known for its power and torque, often used in more robust and off-road oriented e-bikes.

Building an e-bike with a Bafang Ultra motor is generally not a beginner DIY project. It typically involves starting with a frame specifically designed for this motor, as the Ultra is larger and more powerful than standard mid-drive motors. These types of builds are for experienced e-bike enthusiasts looking for maximum performance and are willing to invest more time and money.
Making the Right Choice for Your Schwinn Cruiser E-bike
Ultimately, the decision of whether to DIY convert your Schwinn cruiser or buy a pre-built electric cruiser bike depends on your individual needs, skills, and budget.
Consider DIY conversion if:
- You enjoy hands-on projects and have some mechanical aptitude.
- You are comfortable with research and troubleshooting.
- You are looking for the potentially lowest initial cost (though total cost can rise).
- You want a highly customized e-bike.
Consider buying a pre-built electric cruiser bike if:
- You prefer convenience and a ready-to-ride solution.
- You value warranty and support.
- You want a more predictable and potentially more reliable e-bike system.
- Your budget is sufficient to purchase a quality pre-built e-bike.
No matter which path you choose, the world of electric bikes offers a fantastic way to enjoy cycling with added power and versatility. Whether you’re cruising on a DIY converted Schwinn or a brand-new electric cruiser, get ready to enjoy the ride!
