Small ebikes have a big appeal for urban lifestyles, and DYU offers a city electric bike for nearly any rider.
For riders who prefer the smallest options, the DYU D3+ or DYU S2 both prove that you don’t need 20-inch plus wheels to get where you’re going.
The smaller S2 comes with 10-inch wheels, while the in-demand D3+ ships with 14-inch wheels. For those who need a bit more legroom, the DYU R1 bike ships with 20-inch wheels.
All three bikes fold, making them ultraportable. All three DYU electric bike models also ship disc brakes for fast-stopping power.
DYU Folding eBikes
Often, folding bikes are smaller. Compact size helps with storage and transport, but it’s important to ensure the bike fits your height. Taller riders may want to consider the DYU R1 over the S2 or D3+.
DYU S2 Electric Bike Overview
Don’t be fooled by its small size; the diminutive DYU S2 has a 265-pound load capacity. This bike won’t accommodate a standard rear rack, but a seat-tube mounted rack can be used to carry lighter loads. Seat height ranges from 20 inches but can be extended to 28 inches, giving riders a bit more space.
Small folding ebikes like the DYU S2 fit small or mid-sized riders. However, larger riders may want to step on up to DYU R1 discussed later.
The S2’s handlebars fold down, and the seat easily adjusts to the lowest level, giving you a lightweight, compact package you can easily stow when at work or home. Although the DYU S2 boasts a top speed of 15.5 Mph, expect speeds closer to 13 Mph in normal conditions.
The DYU S2 electric bike powered by a 240-watt motor delivers up to 25 miles of range in throttle mode, while pedal-assist mode can take you up to 31 miles. Recharge time is also impressive, with the 10 Ah battery charging in just six hours.
DYU’s S2 comes with a headlight and taillight, a nice touch for under $500.

DYU D3+ Electric Bike Overview
Stepping up in size from the S2, the popular DYU D3+ brings 14-inch wheels as well as a stylish oval-ish frame design. Notice the built-in handle under the top tube. Just fold down the handlebars, drop the seat, and carry the DYU D3+ electric bike with you on the train or bus. It also fits in most cars easily. And at just 40 pounds, the D3+ won’t test your weight-lifting skills.
In many ways, specs for the D3+ are similar to the S2, but there are a few key differences.
Both bikes come with a 360-watt hour battery, but DYU quotes a wider range of battery life for the D3+. Throttle-only mode should carry most riders 20 to 30 miles, although pedal-assist mode extends the range to 25 to 40 miles.
With a minimum seat height of 28″ and a maximum seat extension of 8 additional inches, the D3+ electric bike caters to riders who may not fit the smaller S2 comfortably. Make no mistake; the D3+ is still small, just less small.
Front and rear lights enhance safety when riding, while front and rear disc brakes help ensure stopping power. At less than $100 more than the S2, larger riders may want to invest in the DYU D3+ instead.
DYU R1 Electric Bike Overview
If you read the specs in the overview already, you might be wondering how a 180 watt-hour battery can keep going for up to 25 miles. Part of this magic is accomplished by the built-in torque sensor. Most affordably-priced ebikes use a less-sophisticated cadence sensor. By choosing a torque sensor instead, DYU is able to deliver power to the 250-watt motor more efficiently.
It’s also wise to take manufacturer’s range claims with a grain of salt. If you’re riding on a windy day or have a mix of hills and flat terrain, your mileage range may vary.
DYU cleverly conceals the battery in the seat post, which means you can remove the battery when you park the bike outside. The battery also comes with a lock, so you don’t have to carry a seat around with you if you’d prefer to leave it installed. Front and rear lights help keep you safer when riding.
The R1 also has a few other surprises in store. This DYU electric bike comes with a lock for the brake as well, helping to prevent theft. You’ll also get a rear rack as standard equipment, making the DYU R1 perfect for running errands or tossing a pannier on the pack for shopping.
With the R1’s larger size and frame, its weight carrying capacity is rated at 330 pounds, a step up from DYU’s smaller bikes. A wide range of adjustability for both the seat and the handlebars makes this a versatile bike that can fit most riders.
It’s worth noting that only the handlebars fold. The frame stays put, but the seat comes out easily if needed. You may not be able to carry this bike onto the bus or train like the S2 or D3+, but the folding handlebars make it easier to transport the DYU R1 electric bike in a car.
