Polarna E Bike ~ 700 Mile Review ~ Accessories

[@wb7370]

Very nice accessories you added,that bike is a gem, powerful and looks rugged with that backrack..you turned your ebike into a 5,000 dollar ebike...shout out from Brooklyn

[@nedchristensen7577]

Great video, Sonny. As always, very polished presentation with plenty of detail and links to all the products you mentioned. Thank you!

[@PhantomPanic]

25:00 I am with you on this one. 😃 I live in Panama City, Fl and there is about 40,000 people here. Hardly any ebikes but when I see one I am sure to turn around and say hey. 🚲

I lived in Albany, Ga for 11 years and did most of my cross county biking while living there in the 80's. I use to send some time vacationing on the Gulf shores at Destin, Fl.

[@TraversyMedia]

Can you tell me the size of the seat post i need for this? I cant find it anywhere

[@MrSovrin]

I was thinking about buying the M6 and wanted to know what kind up upgrades and accessories I could put on the bike. WOW you've got yours tricked out. Thanks very helpful video.

[@rhoffmann1001]

Thanks for all the great advice. Never knew they had quick release pedals. Much quicker to to stow my M6 in the trunk of my Challenger. Think I’ll order the free wheel too if it prevents me from spinning when going 30MPH

[@jacobaccurso]

Really did enjoy the video, Sonny. Thanks again for posting. I live out here in Oregon. Lots of hills along the coastal roadways. To get home, I have to climb a rather steep logging road and I’m not sure the bike is going to be able to make it. Haven’t had a chance to put it to the test yet. I’m wondering if it will help to configure the PAS to 1 to 9 for better hill climbing. My instincts tell me that this will only help I on the straight and level, that it won’t add “extra torque“ for climbing. We shall see. I love how you have outfitted your Polana!

[@Onyasix]

Yes, for a steep hill, you will likely be in your highest PAS setting to supply full current to the motor. For hilly terrain the hub motor design is limited in that it is direct drive with only a single gear. That is why the mid-drive motor is a better design for the hills. The mid-drive motor can take the advantage of the bikes mechanical gears and you can drop it in low gears to let the motor's rpms speed on up. Not only does the mid-drive motor take advantage of the bike's multiple gears, the higher rpm helps to keep the motor from over heating which is a problem for the hub-drive motor under prolong loading.

[@Trillville43]

No having multiple pas levels just makes the power curve more steep before you get to the top end. It's literally a personal preference that does nothing extra.

[@johnslist120]

Just wondering if you know the difference between the m4 m5 and the m6. Not very successful getting answers from the seller.

[@joegonzales601]

Hello Sonny thanks for the video. You said you re adjusted Pas numbers since your last video can you tell to what? Thank you

[@danlittleton2020]

I appreciate you taking time to share your experience with everyone. I received my M6 a few days ago. I considered your insights before buying this bike. Must have quick release pedals! Plan to use bike with RV travel and some rough trails at times. Any advice about other quick release flat pedals for trail use?

[@Onyasix]

None other than I have around 6,000 miles using the Lixada and have no issues with them. I did have one fall that bent the crank arm, but other than some scratches, the pedal was not damaged.

[@philaldan2932]

You have a link to your auxiliary battery?

[@youngyeller]

hey mr. whitehurst, question? the battery graph you have for volts and percentages. is that graoh for 2 batterys? i put a volt meter on my m4 with one battery and my readings are not the same?

[@SonriseSunset]

What does your cadense sensor - sense? It isn't a replacement for Polarna's original cadense sensor?

[@NinjaTurtleNumber5]

Hey Sonny, great vids. Have you heard of anyone modifying this version to carry a passenger? I’m looking at this and the Radrunner (as that has passenger addition). Thanks!

[@Onyasix]

No, I don't recall seeing one modified to carry a passenger. But, I see no reason that it could not be done safely. Both the M4 & M6 are advertised to carry a 360 load (this includes the rider). The rear rack on these e-bikes is very sturdy and I could see a padded seat being made to fit the rack. With that and a set of foot stirrups it would be setup for that additional passenger. Two large adults may be pushing the weight limit of the bike, but as long as that weight stays around 320 lbs or less, you would probably be okay.

[@NinjaTurtleNumber5]

@@Onyasix Thanks Sonny. We are both pretty light, so it might work for the occasional ride. Now its between the M3 or M4 for me.. M3 seems very similar to M4 but a few hundred cheaper (feel free to throw out any insight on the M3). Really well done videos, they're great insight.

[@Onyasix]

@@NinjaTurtleNumber5 ~ I ordered my M4 back in June of 2021. At that time it was selling for $1349. The M6 was not out than so I didn't have that decision to make. I've notice that presently the M4 is selling for $1299. That's a hell of a deal. By far the cheapest that I've seen for a full suspension, 20" folding e-bike. The only comparison that I have between the M4 and the M6 is what I've seen on KZbin and the advertised specs. Based on that the only major differences is the motor (re-gen and higher torque) and a higher quality front suspension fork, everything else seems to be the same. If you have the extra $300 and want the couple of extras then go for the M6. If you are looking for a really great deal and money is an issue then go for the M4. Just realize, that even though the M6 is a good deal, it is still close to 20% higher in price than the M4. All I can say is that I'm pleased with my M4 and do not regret purchasing it.

[@rhoffmann1001]

what inner chain guard did you use? I hit a bump and the chain jumped off recently

[@bobstock168]

Hi Sonny. Love your reviews. I'm hoping you can guide me to the best way to contact Polarna regarding a problem with an M6 battery. My wife's bike only has 40-50 miles on it but it won't charge. We've sent a couple of emails to Polarna but not heard back. I would appreciate any feedback you can provide. Thanks! Bob!

[@robozstarrr8930]

like what you did, very nice setup. thinking about getting the M4 for myself, now i know i'll have to save up for all the great accessories you've shown, Question, how happy are you with the M4's rear suspension w/o the suntour seat post? did it really make a difference in comfort after you installed the seat post?... it isn't overkill? thanks

[@Onyasix]

The M4's rear suspension has a low limited of range which is okay for most road conditions. It is also somewhat stiff with a quick rebound. I prefer a softer ride, so for me the addition suspension is not overkill. I prefer the linkage driven suspension seatpost design over the telescope suspension seatpost. I've used both and the linkage driven design give a much smoother and fueled ride. My first/other e-bike is a Lectric XP with no frame suspension. Using the same seatpost on both e-bikes, I find the Polarna to have a much smoother ride which is to be expected. It is hard to compare the 2 e-bikes (apples to oranges) since the Polarna has a full suspension system (front and rear).

[@robozstarrr8930]

@@Onyasix thanks so much.

[@tomkeating2133]

I enjoy watching your videos, very informative and explained in great detail...you added a volt gauge to your bike which is something I would also like to add to my HeyBike...could you explain how this was done...I like to tinker and work on my own toys, but I don’t want to short or burn anything out...thank you...

[@Onyasix]

Connecting the voltage gauge is pretty straight forward. It has 2 connection wires, a positive and a negative. The connection to the e-bikes system can be anywhere between the battery and the controller. The two power leads from the battery to the controller are red (positive) and black (negative). If you don't have any auxiliary battery (as I do), the easiest place to splice into the power wires would be behind the battery connection plug panel off the leads going to the controller. The connection can be similar to the way that I connected my auxiliary battery. See go to 17:00 in my video: kzbin.info/www/bejne/bJnXi2BqjbiVasU . The voltage gauge will NOT require heavy gauge wires since there is very little current passing thru the wires to the voltage gauge. Since I have an auxiliary battery, I spliced into the auxiliary battery wiring harness between the on/off switch and the auxiliary battery harness lead to the controller/power leads.

[@rhoffmann1001]

On the Polarna M6, it uses a cassette rather than a freewheel on the hub

[@DeeRickDup]

Hello Sonny, I purchased my Polarna e- Bike because of your review. I noticed you installed an inner chain guard to prevent your chain from bouncing off. I had the same issue. Was that difficult to install and which one did you buy?

[@stanc521212]

do you happen to know what awg wire they use for the charging port? im looking for fast charger that will work for this bike

[@Onyasix]

No, but most chargers for 48 volt e-bikes are rated at 2.0 amps and a fast charger may be up to 5 amps. Remember that the fast chargers will effect the longevity of the battery. A 2.0 amp charger will take approx. 5 hours to fully charge a fully depleted 10Ah battery. Therefore, a 5.0 amp charger would take approx. 2 hours to fully charge the same battery. Personally, I would not recommend a charger higher than 3.0 amp to maintain the expected life of the battery. Even at 5 amp a 18 awg wire would carry the load. I would likely use a 16 awg wire for an extra margin of safety. 🤔

[@jockwetmiller4692]

I have a question about your old phone and running the GPS and sensor app. How does your phone use those apps if you don't have a SIM chip and service to get the access to those apps' functions? I have my S8 Galaxy that works just fine after AT&T upgraded me to a S10. So the SIM is not active in the S8 and I'd like to use it for the GPS and possibly the cadence sensor.

[@MrSovrin]

He didn't say he had GPS on just the map, but you could probably get it to work without a sim if you are around any free WI-FI connections on you ride.

[@luckyfire3]

I'm writing this as I watch. How does it compare to the lectric

[@Onyasix]

The Polarna is a step up from the Lectric. With the hydraulic brakes, full suspension (front & rear), up graded shifter and derailleur, solid spoke wheels, higher capacity battery (14Ah), and fully programable controller with color display. The Lectric is a good bang for the buck, but the Polarna is a step above with a good bang for the buck. The ride and comfort of the Polarna is better than the Lectric as it should be sense it is a more expensive e-bike.

[@DyLemmaOG]

why do I need to upgrade the freewheel past 20mph

[@Onyasix]

Most riders with a 11-tooth cog high gear will spin out around 20 mph. At 20 mph with a 14-tooth cog high gear, your cadence is 85 rpm, and at 24.3 mph your cadence is at 100 rpm (which is higher than most riders can pedal). At 20 mph with an 11-tooth cog high gear, your cadence is 65 rpm, and at 30.9 mph your cadence is 100 rpm. With the 11-tooth cog at 28 mph, your cadence is 91 rpm.

[@trini_boi2414]

Damn how much that bike weight now with all that accessories?🤔

[@Onyasix]

291.6 lbs bike, rider and gear . . . 23.8 lbs ~ accessories (including 11-lb 20Ah auxiliary battery) 😊

[@Trillville43]

Why not just change the screen on the Lectric?

[@Onyasix]

The Lectric is a good E-bike for the price range of around $1000. The Polarna is a step above, comparable to the Yamee Fat Bear 750S ( $1799) and the Engwe Engine Pro 750W (1649.99). Two months ago, I paid $1349 for my Polarna which was a steal. It is now selling for $1499. As pointed out in the video, the Polarna's controller is very programmable, far beyond the Lectric XP, it's not just a better looking screen. 750 watt motor, full suspension, fully hydraulic brake system, 14Ah battery, 8 speed gearing, solid aluminum wheels, upgraded derailleur and other upgraded components made the Polarna a much better buy for the $350 extra than a Lectric XP V2.0. You would have to ride the 2 bikes side by side to notice the difference in the riding experience. The position of the rider and the crank assembly are 2" lower than the Lectric which makes the Polarna handle better. The solid aluminum wheels (no spokes) are straight and true, where as my Lectric I could never get the hop out of the rear wheel. I love my Lectric XP and the 4500 miles of fun that I have gotten out of it, but I do not regret the change over to the Polarna. One of the major plus factors of the Lectric over the Polarna is that the seller is an America company and you get better customer service from Lectric. But, I figured that to be the case before I purchased the Polarna . . . with open eyes.

[@onyx8186]

Do you know if the landx gesheng ebike is comparable to this polarna ?

[@Trillville43]

You might have also liked the Engwe Pro

[@Onyasix]

The Engwe Engine Pro 750w is a carbon copy of the Polarna M4. Both are manufactured/assembled at the GDS plant in China. The labels and colors are the only difference. However the Engine Pro 750W is selling for $300 more than I paid for my Polarna. 👍

[@Trillville43]

@@Onyasix they're all copies of each other considering their origins but I was looking at the price and the Engwe was cheaper which is why I brought it up.

[@Onyasix]

@@Trillville43 ~ Only the Engine Pro 750W is a carbon copy of the Polarna M4 and cost $300 more than what I paid for my Polarna. All other Engwe folding e-bikes are cheaper with fewer options and cheaper components.

Air horn and a pepper spray !! lol you need a mount for an AK-47 😎😎

[@blueburaq]

How's reliability on the bike? Any mechanical problems?

[@Onyasix]

I now have over 1,300 miles on the Polarna and have not had any serious problems or issues. Out of the box, I did experience a knocking sound from the freewheel. I replaced the stock 13-28t freewheel with an 11-32t freewheel and the knocking sound was no more. I was going to replace the freewheel anyway so this was not an issue for me. The controller had a couple of hiccups the first few rides, but I did a factory reset and have had no more issues with the controller. There is a potentially serious issue with the fenders on the M4. On the rear fender, the front angle bracket may/will break. This can cause the fender to bind the rear wheel and I've heard of several M4 owners crashed because of this. I have replaced the angle bracket with a stronger one to prevent this happening with me. I had an Lectric XP (my first e-bike) prior to the Polarna. The Polarna is a step above the XP. I paid $350 more for the Polarna then the XP and it was worth the extra cash.

[@deonb3812]

Have you tested whether it's waterproof enough to handle rain?

[@Onyasix]

No I have not it tested it per se, but I have been caught out it some heavy down pours for a short period of time. No problems. I know that the controller display is rated to be water resistant for what ever that's worth.. I heard several others say that they have not had any issues riding in the rain.
