Written Review

UPDATE! It appears that Polaris is no longer working with the manufacturer who designed and built these electric bikes, but that company is now selling their own line as PIM (Power in Motion) and you can connect with them through their official website at www.pimbicycles.com to possibly get replacement batteries, chargers, and other hardware. The following review stands on its own and represents the Polaris bike as I experienced it at the time.

The Polaris Strive electric bike offers a unique combination of efficiency and power. On the one hand, you’ve got a 450 Watt brushless geared hub motor paired with ~30 Volts of power which is on the higher side of mid-level. On the other hand, you’ve got regenerative braking paired with a fancy control system designed to actually limit top speed but extend range and ride time. Compared to bikes with similar motor and battery specs, this one feels a little slow and weak. It’s really meant for efficiency and range, and it accomplishes that pretty well but comes at a high price point that for me left something to be desired.

The Strive weighs just 53lbs including the battery pack which is mounted to a rear rack. That’s pretty light considering all of the features it has along with the front shock absorber. Thankfully, Polaris did not use a bolt-on rack to integrate their battery. Instead, they welded it directly onto the frame. It’s the kind of battery mounting design that many other ebikes go for as well but it does create a rear-heavy feel and makes the bike harder to lift from the middle when mounting to racks etc. The good news is, if you get the high-step version of this bike it’s actually possible to mount to cars and busses. Most of the other models from Polaris lack a straight top-tube so that might be a deciding factor if you’re choosing between the three models.

This bike rides pretty quiet and the sprung seat and front shock smooth out minor bumps in the road. The battery pack is encased in plastic which mounts directly onto the metal rack and because of this, there is some rattling noise. The spring loaded top rack is kind of weak and doesn’t offer a lot of storage capacity but could help with mail or other thin light weight objects. The unique square tubing and battery pack limit what kind of panniers you can use with this bike and I recommend a “slung over” style pannier set for best performance. One of my favorites is the Basil Elements.

A good word to describe this bike is “controlled”. It’s smart, efficient, relatively light and potentially powerful but not directly satisfying. The three modes of pedal assist are the best feature here and really let this bike reach its full potential, they just don’t feel the same as a heavier more powerful ebike. This has actually been described as a benefit to me by Polaris representatives who were trying to design a system that didn’t feel so jerky when pedaling. I tend to like the feeling of torque however and the Strive is a sportier model so it would be nice if the thumb throttle had more kick in it and could reach higher top speeds. Remember, even if you do pedal faster than 18mph the bike actually kicks in regenerative braking so it slows you back down in favor of extending range.

Taking into account the relatively high price point of this bike, the technology and offering may be right for some but it’s definitely not for everyone. For people who enjoy a smoother feel, lighter frame and solid company reputation, this bike could be a fit. But keep in mind, this is the first generation of the Strive and Polaris worked with a third party company to create it. For those who like the idea of a smooth ride but might benefit from fenders, chain guard and upright positioning I recommend the Meridian from Polaris over the Strive. All in all, the Strive is one of the few bikes out there with regenerative braking and its unique torque sensing system is in a class all its own.


  • Rear rack and battery holder are welded onto the frame reducing rattling and wear
  • Front and rear disc brakes provide plenty of stopping power, front shock and seat springs smooth out the ride
  • Computer is easy to use, provides some fun extras such as carbon footprint savings
  • Rapid fire trigger shifters work well and are my preference vs. twist shift on other ebikes, especially for the sportier Strive model that is setup like a mountain bike
  • Advanced computer system provides smooth acceleration and regenerative braking
  • High end Lithium ion battery will last 1,000+ cycles and reduces overall weight of bike
  • Polaris is a well established brand with experience building other light weight vehicles like motorcycles and snowmobiles
  • Plastic chain guide helps keep the chain on track when riding and using mid-drive
  • The high step version of this bike is easier to lift, mount to cars and other racks because of the open triangle and straight top bar
  • Built in water bottle mounting eyelets


  • Rear mounted battery puts weight up higher (like many ebikes) but means the bike is Rear-haevy and a bit less stable
  • Drive system leaves something to be desired in terms of peppiness
  • 18mph top speed motor may be frustrating for those wishing to go faster down hills or just in general
  • Expensive price point considering the motor power and battery system
  • Plastic battery pack design can rattle around more than an integrated design
  • Rear rack is not ideal for clip on panniers, works best with double sided ones that lay across the rack.

I wanted to comment about a few things said in the article. Firstly; the written specs are correct where it states it has a 450W motor, but in the video, he says it only has a 250W motor. Also, as far as down hill speed, you can go as fast as you want with no restriction from the motor (while it is charging over 18 mph). During throttling on level ground it has a maximum unassisted (by pedals) “legal” bike path motor speed of 18-19 mph. You can pedal right past that with no restrictions or being “restricted” or held back. I was doing 47 mph down the hill near my house (pedaling/coasting past max motor speed). And when you exceed 18 mph it is charging. He comments that it has speed restrictive “regen braking” at 18 mph speed which doesn’t make sense. It will charge during braking AND when you are going faster than 18 mph. I have a lot of hills where I live, but have never had the battery go below 2/3rd’s of it’s full charge range only requiring about 45 minutes to fully charge at that point. I also like being able to take the battery out of the bike with the key lock and charge it inside with the handy included adapter if you want (you can also charge with the battery in the bike). I have over 500 miles on my Polaris Strive (upper horizontal bar some call “mens” version) and absolutely love it! The model with the lower frame design (some call them a girls/womens model) is the Strive “ST”. Something else I see on the internet on these is that they retail for either $2999 or $2499. They actually retail at $1999! Remember; if an eBike goes faster than 20 miles per hour on motor (unassisted) and has bigger than a 750W motor, it makes them illegal on bike paths and sidewalks across most of the US states. Some states have their own special rules, so check before purchasing. If you are only buying an eBike to use battery power and hardly pedal, you should probably get a scooter or mo-ped. But then you have possible licensing, insurance, tags and no bike path or sidewalk access. Don’t we all need a little more exercise? This Polaris eBike is whipping me into shape using the pedal assist and I’m loving every second! The Polaris eBikes are very nice high quality units and are not near as bad as this review might suggest. Thanks for listening.

Thanks for the post Roshan. Hope your eBike company, Biktrix is doing well. We're not really in the business of trying to spread falsities and negativity about other companies. It's easy to do in this day and age but we'd rather devote time and resources into bike building.
In response to David's comment, we certainly haven't tried to mislead anyone as to our whereabouts. The majority of our customers know very well that we actually operate in China AND the US, largely due to all the videos we've posted pertaining to the fact.
The truth is, we could easily be based in the US. Rob is from Sacramento and I love the US (UK citizen). We'd love to be based there full time but in the interest of ensuring the highest quality products possible at the most competitive price, that just isn't practical. Living and working in China is incredibly demanding but we're more than willing to make the personal sacrifice in order to make FLX succeed.
We're in contact with all of our factories every single day. The lack of time difference makes it far easier to operate and we regularly jump in the car and go and visit our factories. Not just a few weeks for production but for every minor design change / pre production meeting / conveyance of any important idea etc etc etc. Constant communication and supervision is absolutely critical out here if you strive for perfection.
Rob has been in China for seven years now and myself, the last three. I rotate for three months in Shanghai and three months in California. Guess which location I prefer?
When containers 5 and 6 were delayed, Leah and I drove 7 hours from the FLX office / house in Rohnert Park, California to our fulfillment center in LA. We resolved the issue and then drove the 7 hours back that night. Fly in from China? No idea where that idea spawned from but it's 100% incorrect.
We're officially registered in the US and the UK and are therefore completely liable in both countries. It's not just legal liability though, we also have strong personal and moral ethics (hence you won't find us bad mouthing other companies... online at least anyway).
I think this post is a little old now which is great for us as we can look back and prove that any warranty claim or any other customer concern matter has either already been resolved or will definitely be resolved soon.
The 415 number is indeed a local SF number. We set that up as initially, we didn't have anyone in the US when I was in China. The company started off with just Rob and me with a dream. Instead of using our Chinese numbers, which would have cost a fortune for our backers to reach us on, we thought it was reasonable to set up a call forwarding service so our backers could call us on local rates. We answered that phone religiously at all hours, day and night. Even when sleeping on the floor in our makeshift office in the main factory during the early days. Not sure how that can be viewed as dishonest?
Honestly hope is doesn't look like we go back to China occasionally to 'kick butt' at the factory. The reality is, we're here 'kicking butt' at all our factories all of the time. This might not make sense to some people who have the fortune of living full time in the US or Canada (Roshan), but in a few years we'll prove that this sacrifice will have all been worth it by delivering the best eBikes in existence.
Thank you.

Optibike Celebrates Ten Years

Dear Dan

It is official, Optibike has now been building and selling electric bikes for 10 years! It seems like yesterday when we loaded our first Optibike 400 into the waiting truck for its trip to South Africa.

Optibike is now the oldest manufacturer of electric bikes in America! Today we still focus on quality and performance first. We strive to be the best, not the biggest and results show it.

Now we have sold bikes old over the world from Russia to Indonesia to Brazil. In all, people in over 28 countries have bought an Optibike.

While Optibike set the standard for the electric bike industry of what performance and quality meant, what always was most fulfilling to me was how we changed peoples lives.

We have had people lose 80 pounds, end their use of prescription drugs, rekindle their relationships and have the time of their life as they remembered what is was like to be a a kid again and feel completely free and energized. This is amazing.

Over the years, Optibike has been featured on ESPN, CNN, The Today Show, National Geographic Adventurer, and in The NY Times.

Optibike has always been ahead of its time. In fact, or first model, the 400 in 2007 has higher performance than the popular European systems today. But we didn't sit still, as the R15 has 3.8 times the power of the 2007 model!

Our Electric Bikes are custom built with artisan quality one at a time, and they are the worlds fastest and longest range High Performance Electric bikes available

Over the years our product line has expanded and we currently offers electric bikes for commuters, performance enthusiasts, and off roaders. We are the only company to offer a diverse line of bikes in different power, performance and price categories.

I feel proud when many of our customers are ordering their 4th and 5th Optibike. They started with the first Optibike released and are now on the latest R15. This says a lot about Optibike quality and performance.

I just spoke with a customer who has the original 2007 400 with Nickel Metal Hydride battery and it is still running strong after 10 years.

Some of the highlights of the last ten years are below. I hope you enjoy reading them. They have brought back some good memories to me.

Jim Turner

Optibike Inventor.

Jim Turner finishes his 1st Optibike prototype.
After first investigating hub motors in 1996, Optibike developed this first mid drive unit in 1997.

This unit featured 24 volts with a 15 amp-hr lead acid battery and about 350 watts of power.

The motor was off board on the crank axle and drove through the final drive chain (other companies still use variations of this design today). Optibike did not file any patents on this design as it did not meet the final design objectives of high power in a small efficient package.

This prototype validated the superior performance of the mid-drive and led to the development of Optibike MBB and several patents. The MBB design integrated the mid drive into a small compact package that it is today.

The MBB has evolved since then, with now over 3X the power of the first units and superior reliability. All Optibike MBB's are still made in the USA.

The first prototype pictured here, without suspension, also convinced us of the need for suspension.

First Production Optibike Built
After almost a decade of development the first production Optibike was finished in late 2006 for shipment to South Africa.

First Optibike being Loaded for Shipment to South Africa
After 10 years of development, we were finally in production!

The Model 400 had 400 watts of continuous power, 90 Newton Meters of torque and a 37 volt 13 Amp Hour nickel metal Hydride battery that weighed 17 pounds.

Check out the R15 at the end of this email to see how Optibike performance has increased four times in the last ten years.

Jeff Baum buys an Optibike R8 to ride his breathtaking 10 mile commute through the snow from Frisco to Breckenridge.
He goes up and down snow covered winding roads in the Rockies - to his job as the executive director of the Breckenridge Music Festival.

For most of his 10 years at the Festival, he had driven a standard gasoline -powered sport utility vehicle. Then he found the freedom of the Optibike.

It takes him a little longer to get to work, but the bike is more dependable, more nimble, more invigorating and just more fun than the S.U.V., he said. (and yes, he does take his skis with him)

The New York Times names Optibike - 'The Ferrari of Electric Bikes'
The New York times wrote an article on electric bikes featuring Jeff Baum and sales took off. In a matter of a few weeks, Optibike sold out its next 15 months of production. In the article, the Optibike was referred to as the Ferrari of Electric Bikes.

Jim Turner is awarded 'Inventor of the Year'
At the Colorado Inventor Showcase - In recognition of exceptional ingenuity, creative genius, and product development skills, Jim Turner and the Optibike were awarded the "Inventor of the Year".

The Colorado Inventor Showcase was Sponsored by the DaVinci Institute.

Optibike featured at California Academy of Sciences
In 2008, the Optibike OB1 was featured in the "Future of Transportation Display" at the brand new California Academy of Sciences in San Francisco. Originally scheduled for one year, it was kept for over 2 years as one of the most popular attractions.

Optibike Releases First Lithium Ion Battery in E bike
Optibike pioneered the use of Lithium Ion batteries in E bikes. Back in 2008 we released the first 37 volt 20 Amp Hour Lithium Ion battery. This is the technology that Tesla uses today. Many of these batteries are still running strong today.

DeMarcus Ware of the Denver Broncos (then of the Dallas Cowboys) buys an Optibike to use as of part of his training as a lineman
DeMarcus says: “I’ve been riding my Optibike OB1 for over a month, and I can’t stay away - I absolutely love the bike. I ride it every single day as part of my training regimen. In the suburbs or on the hills at training camp, this bike will be with me. It is the perfect cross-training tool for me because it allows me to get a great workout yet still enjoy what I’m doing. I would recommend an Optibike to anyone who has those same goals.”

-DeMarcus Ware

Optibike Wins Pikes Peak Hill Climbing Event
In 2011 a group of Optibikes took 1st to 7th places in the Pikes Peak Hill Climb Event, climbing over 7,500 feet in 24.5 miles from Manitou Springs to the 14,100-foot summit.

1st place was John Sagebiel with a time of 1:06.45. The 1st 'other' brand of e-bike took over 3 times as long as John. As of this date, no one has beaten Johns time.

Velodrome Pacer uses an Optibike to lead the packs
Optibike, the world’s leading high performance electric bike, is circling Boulder’s velodrome and stirring much excitement.

Optibike has found its place as a coaching and pacing tool in Boulder’s renowned velodrome.

“The Optibike has been really useful to us" Tim Kyer said “Our track here (in Boulder) is small and makes for a unique dynamic ride. Optibike is helping riders learn the smooth pedal stroke and a consistent speed in and out of turns”

“We are using the 1100R model and are seeing a lot of ways that Optibike is used for a training tool. We can get through multiple workouts and groups on one battery charge.”

In other indoor cycling centers, electric and gas scooters are used. However, there is exhaust and emissions from gas machines.

The Optibike is the first electric bike powerful enough to lead a pack of very powerful cyclists and replace the scooter/motorcycle derny.

Optibikes have been sold to customers in 28 countries
By 2011 Optibike had delivered bikes to riders in 28 countries. The riders were from all walks of like, with a common interest to have a high performance bike that changed their lives. They all ordered their bikes direct from Optibike and each one was hand built one at a time, just like today.

Rock and Roll Hall of Famer, Steve Winwood (Traffic, Blind Faith) invites Jim Turner to a Denver concert after buying an Optibike for his band manager James in England
Band Manager, James received his Optibike as a birthday present from Steve and uses it to commute the 16 miles to the studio each day with 2000 feet of climbing. Lots of days of rain and drizzle as it is England.

[update] I've enacted many of the changes discussed in this thread, feel free to chime in if you've got further suggestions! Thanks again for all of the great input :)

Hey guys and gals, I appreciate your involvement with EBR in the community and want to share my thoughts on some updates and get your feedback :)

I'm a huge fan of the UK Pedelecs forums and Grin owned Endless Sphere. In recent months (and really years) I think the EBR space has become a bit overwhelming with so many brand sections. I designed it this way to align with EBR eventually with content from the forums being shown in a sidebar widget on the site in each respective brand area. We're on the brink of making that happen but I've realized I could put brands in a sub category here and that would keep the homepage MUCH cleaner.

Pasted below is an updated list of sections including some new names. Some of this imitates the other ebike forums and my plan includes renaming the community to "forums" since people seem to get that more... I get emails occasional from people asking if the site has forums and I'm like "yeah! The community XD" so hopefully this helps. Anyway, I value your input on what additional forums to add AND whether for sale used and for sale new makes sense? It could be a place for company's like Crazy Lennys, Propel, Performance Bikes etc. to post without distracting other threads. This has been a difficult balance to strike... I strive to limit my own ads here and pay over a thousand dollars of my own money each month on host and moderate this space. It feels bad to go to all of that effort then possibly alienate the paying advertisers while promoting show rooming indirectly and gouging prices. On the flip side, the world is a marketplace and last-season models, used stuff and promotions do have their place. How should this be handled? As always, THANK YOU ALL for making my dream of sharing ebikes, connecting people and promoting healthy living a reality by spending time here and supporting EBR. And thank you @Ann M. for all of your contribution as a super mod.

what type of charger does this use

4 years ago

I think in some ways they have a good idea, like sharing the same battery and drive system to keep costs low and make parts easier to replace but overall, I was underwhelmed with the designs and the same price for all of them when some have fenders and accessories and others don't.

Who is running the show at Polaris? This e-bike is going to be a flop. I am an American, give me some power! And I get thirsty when I bike, what no place to put my favorite water bottle. What were they thinking? I also love the noise it makes...NOT. How will you know when it is about to breakdown, when it already sounds broke. Let's hope they scrap this bike soon and get serious.
