Best Budget E-Bikes Under $500: Amazon Gems

In This Guide

The sub-$500 e-bike market is a minefield of proprietary parts and questionable batteries. We filtered the noise to find three UL-certified platforms that are safe, modifiable, and worth the investment.

  • The Reliable Standard: Jasion EB5
  • The Commuter Choice: Isinwheel M10
  • The Premium Upgrade: Heybike
  • Technical Deep Dive: 36V Limitations & Battery Safety

Buying an electric bike for under $500 on Amazon.  The "Amazon Wars" have driven prices down while forcing quality up—specifically regarding battery safety and UL certification. I personally purchased an electric bike from Amazon for under $500.  I ordered it from another company, but when it arrived the bike displays Isinwheel and looks like the M10 model.  I love it.  It is comfortable.  The pedal assist is responsive providing a great ride.  

For the Maker community, these bikes represent incredible value. You are essentially buying a rolling chassis, a hub motor, and a lithium pack for less than the cost of sourcing the raw components. After filtering out the brands with high return rates, we found three reliable platforms ready for your daily commute or your next IoT modding project.


Managing Expectations

Before you click "Add to Cart," understand the physics of this price bracket. You are not getting a Bosch mid-drive.

The 36V Ceiling

Almost all bikes in this tier run on 36V systems. While they market "500W Peak," the voltage sag on steep hills is real. These are best suited for flat terrain or moderate inclines.

UL 2849 is Mandatory

Do not buy a generic "white label" bike without UL certification. The brands listed below (Jasion, Heybike, Isinwheel) have compliant electrical systems, significantly reducing fire risks.


1. The Best All-Rounder: Jasion EB5

Best For: Commuters who want a standard, proven platform.
Est. Price: $399 - $450 USD

The Jasion EB5 has effectively replaced the older generation of budget bikes as the gold standard for entry-level riding. It features a relaxed geometry and a 26" frame that feels stable at speed.

Spec Value
Motor 350W Brushless (Peak 500W)
Top Speed 19 MPH (Unlockable via display)
Suspension Front Fork Shock (Basic coil spring)
Tech Note: The EB5 uses a standard controller interface. Makers have successfully tapped into the lighting circuit (which runs at pack voltage) to power auxiliary IoT devices like GPS trackers using a simple buck converter.

2. The Modular Commuter: Isinwheel M10

Best For: Ease of maintenance and battery swapping.
Est. Price: $399 - $489 USD

The Isinwheel M10 is a dedicated commuter built on a standard 26" mountain bike frame. Unlike smaller folding bikes, the M10 offers full-size geometry which handles potholes much better.

It features a removable waterproof battery integrated into the downtube, but not permanently sealed inside. This is a massive advantage for Makers: you can easily remove the pack to charge it at your desk, or 3D print a custom bracket to mount a secondary parallel battery for double the range.

Why Makers Like It:

  • Standard Parts: Uses standard 26" tires and tubes available at any Walmart or bike shop. No proprietary rubber here.
  • Accessible Wiring: The controller box is often externally mounted or easily accessible near the crank, making controller swaps (for 48V upgrades) much easier than frame-integrated units.

3. The "Stretch Goal": Heybike

Best For: Riders who want Shimano parts and reliability.
Est. Price: $499 - $599 USD (Often on sale)

Heybike sits at the premium end of the budget spectrum. While their standard entry-level model sometimes creeps over the $500 mark, it is frequently discounted. It is the most "bicycle-like" option on this list, featuring full-size 27.5" wheels and a 7-speed Shimano drivetrain.

The Modder's Advantage: This Heybike model uses very standard bicycle components. If you bend a derailleur or wear out brake pads, you don't need to order from China—you can buy replacements at any local bike shop. The external battery mounting found on this frame is also much easier to upgrade or replace than the integrated frame batteries found on other models.
