BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.
We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews
We have read all expert and user reviews on the Euybike S4. In summary, this is what cyclists think.
8 reasons to buy
- Experts and owners praise the comfortable ride over pavement and light off-road terrains.
- Two reviewers highlight the even distribution of power across PAS levels.
- The hydraulic disc brakes provide good stopping power in testing.
- The S4 comes with fenders, a seat extension, and lights with brake activation.
- Experts appreciate the nimble handling.
- A 200lb tester gets 36.6 miles of throttle-only riding in a range test in the city.
- The included rear seat extension can be used for a passenger or as space for taller riders to shift back.
- S4 owners can easily customize motor settings such as top speed, PAS sensitivity, and power intensity through the display.
14 reasons not to buy
- Testers report a four to eight-second delay for PAS to kick in or re-engage after coasting, and up to three seconds for it to shut off once pedaling stops.
- With a 35" seat height, riders under 5'9" will struggle to mount this bike, and riders over 5'10" won't get proper leg extension.
- Tests show PAS 1 reaches around 17mph, which is high for the lowest assistance level and limits control in tight urban environments.
- The motor's power of 1,000W and the bike's top speed of 31mph both exceed legal e-bike limits.
- In a throttle-only climbing test, the S4 performs worse than similar bikes tested by one reviewer.
- Experts say ghost pedaling starts around 20mph.
- The front brake rotor on one test bike arrives warped, and several reviewers report squeaky brakes.
- The included 2A charger takes almost 13 hours to charge the large 25Ah battery.
- A reviewer and a buyer both find the seat extension doesn't line up correctly with the frame mounts, complicating installation.
- The display reads between two and three miles per hour above external speedometers.
- The product webpage provides contradictory information, such as two different payload capacities (330lb and 400lb).
- The S4’s low water resistance rating of IPX4 means it shouldn't be ridden in heavy rain.
- A reviewer finds the bulky dual-crown fork increases the S4's turning radius.
- The S4 is not UL-certified.
Bottom line
The Euybike S4 is a moped-style e-bike with dual suspension, a 1,000W motor, and a 1,200Wh battery. Experts praise the strong brakes, agile handling, range, PAS and throttle power customization options, and overall comfort. Tall testers find pedaling uncomfortable, and the 35" seat height means riders under 5'9" probably won't fit. Other issues include underwhelming throttle climbing performance, ghost pedaling at 20mph, severely delayed PAS, long charge times, and an inaccurate speedometer. The contradictory product specs information and lack of safety certification are also worrying. Despite these issues, reviewers consider the Euybike S4 good value for a moped-style e-bike at this price point.
