How this e-bike scores for different riding styles

Off-Road Adventure
85/100

Excellent off-road capability with 26" x 4" fat tires, 1000W peak motor, front suspension, and dual disc brakes. The carbon steel frame and 330 lb weight capacity provide durability for rugged terrain.

Recreational Leisure
82/100

Great for casual rides with cruise control, 5 riding modes, comfortable saddle, and fat tires for beach/sand riding. The 60-mile PAS range allows for extended leisurely trips without range anxiety.

Daily Commuting
78/100

The 55-60 mile PAS range and 25 mph top speed make it suitable for most commutes, with integrated lights and rear rack for cargo. However, the 68.3 lb weight and non-foldable design limit portability for multi-modal transport.

Cargo & Utility
75/100

Rear rack supports 60 lbs of cargo and the 330 lb max weight capacity accommodates rider plus moderate loads. However, lacks specialized cargo features like panniers or extended rear platforms found on dedicated cargo bikes.

High Performance
68/100

The 1000W peak motor (500W rated) and 25 mph top speed are respectable but fall short of true high-performance e-bikes. The 68.3 lb weight and carbon steel frame limit acceleration and handling for performance-focused riding.

Compact & Portable
20/100

Poor fit for this use case as the bike is not foldable, weighs 68.3 lbs, and features bulky 26" fat tires. The large frame makes storage and transportation challenging in tight spaces.

Our Verdict

The Funhang EB-S1 electric bike is a really good deal for anyone who wants a fat tire e-bike without spending a lot of money. At $355, you get a bike that can go 25 miles per hour and travel up to 60 miles when you use the pedal assist. The big 4-inch fat tires are the star of the show - they let you ride on sand at the beach, through snow in winter, or on bumpy trails in the woods. The bike also passed UL safety tests, which means experts checked it and said it's safe to use. You get useful extras like front and back lights so cars can see you at night, and a rear rack that holds 60 pounds of groceries or other stuff.

This bike works best for people who want to ride for fun on weekends, explore trails and beaches, or ride to work if they have somewhere to store it. The 60-mile range means you won't run out of battery on longer trips. People who weigh up to 330 pounds can ride it safely. It's perfect if you live somewhere with bike paths, trails, or want to ride on different types of ground. The cruise control and 5 riding modes let you pick how much help the motor gives you, from doing all the work to just giving you a little boost.

However, this bike isn't right for everyone. If you live in a small apartment or need to carry your bike up stairs, the 68-pound weight will be a problem. People who take the bus or train to work can't fold this bike up like some other models. The battery takes 6.5 hours to charge, so you need to plan ahead and charge it overnight. The carbon steel frame can get rusty if you leave it outside in the rain, so you need to keep it dry or covered. If you need a really powerful bike for super steep hills or want to go faster than 25 mph, you should look at bikes with bigger motors that cost more money.

What We Like

  • Amazing price at just $355 for a bike with fat tires, big battery, and UL safety certification - hard to beat this value
  • Goes up to 60 miles on pedal assist mode, so you can ride all day without worrying about the battery dying
  • Fat 4-inch tires let you ride on sand, snow, gravel, and trails - basically anywhere you want to go
  • Comes with helpful extras like front and rear lights for night riding, plus a rear rack to carry 60 pounds of stuff
  • Really good safety ratings with 4.6 stars from 207 buyers, plus it passed tough UL safety tests

What Could Be Better

  • Pretty heavy at 68 pounds, so you'll have a hard time lifting it up stairs or loading it on a car rack
  • Takes 6.5 hours to fully charge the battery - that's almost a full workday of waiting
  • Carbon steel frame can rust if you don't take care of it, unlike aluminum bikes that don't rust as easily
  • Can't fold up, so you need a big space to store it at home or work
  • The motor is only 500 watts normally (1000 watts at peak), which isn't super powerful for steep hills compared to pricier bikes

Standout Features

26" x 4" fat tires
Exceptional all-terrain capability - wider than standard 2-2.5" tires, enabling beach, snow, and trail riding
UL 2849 certification
Above average safety standard - many budget e-bikes under $500 lack official UL certification
$354.99 price point
Outstanding value - 40-60% less expensive than comparable fat tire e-bikes with similar battery capacity and features

How far can this bike go on one battery charge?

It can go 30-35 miles if you use just the motor without pedaling, or 55-60 miles if you pedal along with the motor helping you. How far you actually go depends on how much you weigh, if you're going uphill, and how fast you ride.

How fast does this electric bike go?

The bike can go up to 25 miles per hour at top speed. You can control how fast it goes using the different riding modes and the 7-speed gears.

Can I ride this bike in the rain or on wet roads?

Yes, the battery is waterproof rated IPX5, which means it can handle rain and wet conditions. However, the carbon steel frame can rust over time if you don't dry it off and keep it protected from water.

How much weight can this bike carry?

The bike can safely hold a rider who weighs up to 330 pounds. The rear rack can also carry an extra 60 pounds of cargo like groceries or a backpack.

Do I need to put this bike together when it arrives?

The product details don't say exactly how much assembly is needed, but most e-bikes arrive partially assembled. You'll likely need to attach the front wheel, handlebars, and pedals, which usually takes 30-60 minutes with basic tools.
