Polarna tech specs:

  • Motor: 750W rear hub motor in cast wheel
  • Top speed: 28 mph (45 km/h)
  • Range: Claimed up to 45 miles (72 km), more like half of that with fast riding
  • Battery: 48V 12.8Ah (614 Wh)
  • Weight: 68 lb (31 kg)
  • Wheels: 20 inches with 4-inch fat tires, cast rims instead of spokes
  • Brakes: Logan hydraulic disc brakes (160 mm rotors)
  • Suspension: Front and rear
  • Extras: Included fenders and rear rack, 8-speed transmission, front, and rear LED headlight and tail/brake light, color LCD display, kickstand

The company claims that it reaches 32 mph, but after de-limiting the bike via the display I was mostly hitting 28 or occasionally 29 while riding on flat ground, with occasional spurts into 30 mph territory. Perhaps they had the help of a tailwind when they quoted it.

The color LCD screen is easy to read both during the day and at night, and it actually looks quite good. I’m so used to monochrome screens that color displays often still catch me off guard. It’s definitely a sharp-looking screen.

The headlight though, goes the other way. As nice and bright as the screen is, the headlight is a bit lackluster. It works, but it doesn’t really light your way that well. It’s a be-seen light and is pretty much only meant to let cars know that you’re there. That’s fine on an e-bike, but for something like this that is meant to travel off-road as well, a brighter light could have been nice.

The folding mechanisms are basic and commonplace, nothing fancy there. It folds at the handlebars and in the middle of the frame. That’s how 95% of folding e-bikes work and it’s just fine. It’s not space-age, but it works well. And it’s nice and sturdy, which is exactly what you want on a bike that you’ll be bouncing over berms all day.

The only downside to the folding aspect is that you are limited on battery capacity. The 615 Wh battery is acceptable, but not huge. I’d say that’s only slightly below average for e-bike battery capacity today.

The company claims you’ll get 45 miles of range, which is laughably optimistic. I was getting closer to 20-25 miles on throttle-only riding. Granted, I was riding pretty much full-out, but still. Don’t expect to get close to 45 miles unless you’re slowing down and adding some good pedal power.

FOLDING FAST AND COMPACT

  • A ‘folding’ bike should certainly be good at folding… This is a strong point for the Polarna  205 which folds simply and in seconds. Whether you’re commuting, going on holiday or having a ride by the coast, the bike folds compactly and securely in car boots and even on public transport.

48V 750W BRUSHLESS MOTOR

  • Boasting the latest sinewave controller, it feels smooth, responsive, and powerful. The high-quality 750w rear motor assists when pedaling up to 28 mph. For those steep hills or windy days. Performing superbly in any urban environment, the bike’s rear shock absorber and fat tires provide a consistently comfortable ride.
  • Pure Comfort-Full Suspensive

From its easy-on, easy-off step-thru frame, to HeadShok fork and Full suspension, everything on the Polarna EBIKE M4 is engineered to give you the most pleasurable ride possible, from the city streets to the open road.

  • Hydraulic Power-off Disk Brakes

When you are riding on the street and someone or a pet runs out of the street, the value of the brake system can be reflected. Provide safe protection for your riding

Is it worth getting an ebike?

Well, electric bicycles offer the same great benefits as traditional bicycles including cost savings (no licensing or insurance required), improved well-being, and connection with community. The real advantage to e-bikes in my view is efficiency in climbing hills or fighting the wind combined with better range.

How much does a good ebike cost?

Article summary. Generally, electric bikes will range in cost from a low of $600 to over $8000. Not many quality e-bikes can be had for under $1000, with most mainstream ebikes costing between $1500 – $4000. Almost 80% of the e-bikes I compiled info on were under $4000 MSRP.

Are e-bikes better than regular bikes?

They’ll Get You Into Much Better Shape

While e-bikes will make it easier to ride your bike when you hit the road, you’ll still be pedaling just as much as you would on a regular bike. You’ll also likely be traveling longer distances on your e-bike, which means you’ll pedal even more than you normally would.

How long do ebike batteries last?

Between 3 and 5 years

You should typically expect a battery to last between 3 and 5 years if it is well maintained. (A lithium battery will slowly lose its capacity over time, even if it’s not used.) Below are three things you can do to ensure you get the longest usage out of your electric bike battery.

How hard is it to pedal an electric bike?

The main reason that electric bikes are harder to pedal without assist is that they are heavier than regular bikes. Most of this additional weight is from the battery pack, which can weigh several kilograms. With assist, e-bikes are of course much easier to pedal – that is the whole point of electric bikes after all!

What is the difference between an electric bike and an e-bike?

The main difference between a normal bicycle and an ebike is the motor. Pedaling an ebike is less work because they give you power while pedaling, but e-bikes let you go further using less effort.

Should I charge my ebike after every ride?

IMPORTANT CHARGING INFORMATION

It is good practice to recharge as soon as is reasonably possible after the battery goes flat. We recommend charging after every ride, that way your electric bike is always ready for your next outing. Switch off the battery before charging. (If the battery has a switch on it).

How far will an e-bike go on one charge?

With relaxed pedaling expect 22-50 miles on a single charge for most e-bikes. In some cases, you’ll go even farther. We have bikes that are getting 80+ miles on a single charge. The range will also be impacted by the battery capacity, the hills, the wind, and your size.

What happens when your electric bike battery dies?

When your battery is dead, there will be no power to the bike at all. So, your electric headlight and brake light won’t turn on. And you won’t be able to charge your phone (if your e-bike comes with a USB port).

Can you ride an electric bike in the rain?

Electric bikes, just like push bikes, are water resistant and as long as you can see and ride safely in the rain, your electric bike is fine to ride. The batteries in our e-bikes are in a high-quality, water-resistant casing. You don’t need to glad wrap your battery if the weather suddenly takes a turn.

Can you still use an ebike without the battery?

Image result

The simple answer is yes. An e-bike will operate the same as a standard bicycle when not using the motor, whether by choice or because of a flat battery. We’ve reviewed a lot of e-bikes, and we can tell you that riding without the power will impact your ride.
