Voima E-Bike

E-Bike / 190mm / 29″ / MY-2022

More is More. A principle that we strongly believe in at Pole Bicycles. Our ethos is held firmly in function before form and form follows function. The Pole Voima (meaning Power in Finnish) is all of these principles coming together. 

The idea behind the Voima is simple; Ride up, along, and down faster. We worked hard to create a bike with better-pedaling efficiency that had longer travel, the assistance of a motor, and a long-lasting battery range. It’s all about maintaining power transfer from our pedal motion to trail speed mechanically, not only from the assistance of the motor, and with the right suspension kinematics. Our modern suspension design allows us to make the most of pedaling efficiency without a loss of energy. Because of this, the Voima is the ultimate enduro, park bike, long-distance trail rig, and DH play bike all in one. 

The Voima has more power, more travel, and it can cover a greater distance. Sourcing the latest technology, we were able to create a bike that didn’t weigh over the odds and has more range and suspension travel. There are no compromises in terms of suspension kinematics, geometry, or how the bike rides either. Based on a completely new suspension platform – a design that has been tested across both bikes with and without a motor and battery. It has proven to be lively and active but without compromising on pedaling efficiency or suspension dynamics.

The Voima has been designed as the truest form of what we believe an e-bike should be. We never benchmark against other bikes and the Voima is no exception. It is not based on an existing bike model with an e-bike motor and battery adapted into the original design either. It has been designed and created as an e-bike from the ground up. 

What is More?

With 190mm travel front and rear, the Voima is also the only completely CNC machined and bonded 7075-T6 aluminum-framed e-bike in the world. We’ve also designed the frame to be dual crown compatible. Race tested and approved, we already have two e-bike race wins under our belt with the Voima and will soon complete the industry’s toughest EFBE safety testing in Germany. 

“We have everything set here. This beast goes around corners like a snake and hucking to flat is just another day at the office. This bike is a fun machine at the local trails and it can keep up with the big boys at the bike park’s – holy crap it’s fast.”

A big battery that loads from the top of the downtube

Voima has a 725Wh battery that can be changed really quickly if you want to ride in boost mode more. The battery is best positioned on the top of the downtube for ease of access and weatherability. Water is the worst enemy of the electric mountain bike. That’s why we’ve mounted the power inlet at the top. This is how we can secure the inlet ports from water ingress.

The battery cover also has bottle mount tabs for a Fidlock bottle mount. However, if you charge your battery from the external port and ride with only one battery, a conventional bottle holder will do.

Fully covered motor

The Voima runs a Brose S Mag motor and BMZ V10 725W battery. We chose Brose because of the great power delivery without being overpowered. The motor is set completely inside the frame, sheltered from trail elements, a decision made after extensive testing of weatherability during design and development. As a comparison, we also tested the motor completely uncovered and exposed to the elements to make sure that connections between the battery and the motor lasted over a long period of time. The Brose motor delivers power naturally and effortlessly but still has 90NM of torque when it’s needed.

Our research showed that many bash plates under the motors are just not strong enough. Very often the chainrings and motors get damaged. The benefit of CNC’d aluminum is that we can enclose the motor inside the frame without worrying about overheating the motor. The frame extends almost under the bottom bracket and protects the motor from rock strikes and trail obstacles. There are also ISCG-05 holes so extra chainring protection can be installed. There is also room under the motor if anything goes sideways, your motor is safe. Behind the motor, we have a cover that protects the motor from the elements.

Yes SENSEI

We designed the suspension kinematics for bikes that have to have room for a motor or a gearbox. SENSEI pedals extremely well due to a virtual pivot point that hovers near the chain line. SENSEI has a falling rate of leverage ratio (progressive) and a falling rate of anti-squat to keep the pedal feedback low. We have reduced the ground feedback significantly and brought more balance to cornering and jumps. The shock is mounted sideways to minimize the stress to the shock bushings. The whole 190mm of travel can be used with an air or a coil shock and it is versatile for all sized riders.

“Your work will teach its maker,” Leo’s grandfather used to say – a talented self-learned craftsman. SENSEI is Japanese and it means teacher. We named our suspension SENSEI because comes from our relentless testing of different options and learning from them. Our research and testing is our teacher and that’s how we get better every time. Learning from mistakes and accomplishments and adding grit to move forward is what Finnish “sisu” is made of.

With SENSEI we can use 32t front chainring which allows us to have better ground clearance and power delivery. With SENSEI we don’t need to go with big front chainrings that are heavier and more prone to damage. Some claim that a bigger chainring in the front creates less wearing out in the cassette. This is partly true but moving from 32t to 38t with 80 RPM you can only upshift one cog in the cassette. The speed with 38t on 80rpm with 29″ and 10t in the rear is 42.1kph. On 32t the same value is 35.5. However, with 50t the speed difference is only 1,3kph.

Our research says it’s better to go with a smaller chainring because chain breakage is a very common problem on e-bikes. The less power we need from the motor on uphills, the more battery range you will have and you are less prone to chain snap or chainring damage.

SENSEI Kinematics

As a result of our new suspension design, we have improved several things. Our anti-squat value is always ~100% in 30% SAG with all gears unlike some other suspension designs, where the anti-squat value variation in SAG may vary significantly. If you want to learn more about anti-squat, here’s an article that more information.

Our leverage ratio floats around ~2.6:1 in dynamic SAG and that is where most of the shocks are at their best. The leverage ratio is within a falling rate so that we can get a smooth small bump feeling and a good pedaling and cornering platform in the mid-stroke. A falling rate leverage ratio gives a smooth ending-stroke without a harsh bottom out. We have optimized the leverage ratio so that the suspension has less ground feedback and it’s more pleasant to ride seated. Here is more information about our philosophy of suspension design.

“And, it’s beautiful. Pole’s whole ethos is function before form, and form follows function. If that’s not beautiful, then what is?”

Made inhouse in Finland

The one thing we do have as an advantage is our ability to manufacture in-house, in Finland with our own CNC machinery. This puts us not only in a unique position in terms of developing and manufacturing framesets across our model portfolio, but we can avoid any unnecessary delays in production from a third-party manufacturer in the Far East.

The Voima is not only unique in its design and capabilities, but also in the way we move forward in production.

The Voima will be produced as a frameset only for the time being with complete builds coming later in 2021, early 2022 when the global supply chain levels out.  

In the future, our production lead times will be shorter and manufacturing much more efficient. Our goal is to have framesets available in stock as orders are placed. 

Charging port near the head tube

One of the most common problems we discovered during research and development in most e-bike designs was water penetration into the charging ports or poor connections between the battery and socket. We’ve integrated a power inlet close to the head tube of the bike, not only to help ease of charging but also to prevent ingress from water and other trail debris.

A premium product without the Premium Price

Production is due to begin in Autumn, with only K2 and K3 framesets available on a limited basis. 

Framesets cost an introduction price of 5490 € and complete builds coming in at 8490 € and will arrive in early 2022. The after introduction price for the framesets will be 5990 € and complete builds will be 8990 €.

As our experience of CNC machining has developed, expanded, and has been refined, we are now in a position to manufacture the Voima with lower production costs, which in turn can be passed onto the customer in the MSRP.

Sizing

On a bike with such progressive geometry, the question of best sizing is one that we get asked a lot. So, we decided to updated our size naming convention. Instead of S, M, L, and XL we’ve replaced it K1, K2, K3, and K4 (the K stands for Koko, which means size in Finnish)

Taking into consideration height crossovers, we have created a size chart matrix that not only covers the rider’s height but incorporates your riding style too. The result is a simple way for you to best choose the bike size to fit their needs – you’re welcome.

For example, if you are 182cm tall and prefer a bike for all-out speed, we would suggest the size K3. If you spend more time at the bike park or prefer a more agile riding style, take the size K2.

Voima FAQ’s

What is the frame warranty on the Voima? And what warranty is offered on the Brose motor?

All our in-house CNC’d framesets are covered by our limited 5-year warranty for manufacturer defects. Brose offers a 4-year warranty on the S Mag motors fitted to all of our Voima e-bikes. For more information, visit our Product Liability and Warranty Page

Can I buy an extra battery?

Yes! We have an exclusive partnership with BMZ which allows us to sell you an extra battery for use on your Voima. Pricing is still to be finalized, but we’ll have more news coming very soon!

Can I buy a frameset without a shock?

Unfortunately not. We spend a lot of time testing and developing every bike in the Pole range. Each bike is specifically equipped with parts that we have tested extensively so that you can get the best performance out of your bike. 

When will they be delivered?

Voima frameset production will start in Autumn of 2021 at our in-house facility in Finland with an estimated delivery window of September. Production of the complete Voima bikes will start in Spring of 2022, with an estimated delivery soon after. 

I’m not a fan of the brakes, can I get other parts fitted to my complete Voima?

We work with SRAM to bring you the best performing parts and specifications for the bike model. Unfortunately, the ongoing supply and demand issues currently being experienced globally, means we are limited to a specific range of products on the complete builds. However, never say never! It’s always worth getting in touch with us to see if there is anything else we might be able to offer – contact us at service@polebicycles.com

I live in the UK, will the motor be limited to the correct speed for my region?

Each frameset and complete Voima will have the correct firmware to match laws and regulations in each region globally. This will be preset in our factory before dispatch. Don’t worry, we’ve got you covered!

Does the frameset come with a crankset?

Voima framesets do not come with a crankset. With so much choice, we decided to leave it up to you to choose. As long as they are e-bike ISIS compatible, you’ll be hitting the trails in no time!

Can the Voima be set up as a Mullet e-bike?

Although the bike has been developed around a complete 29” wheel set up, it is still possible to run it as a Mullet. 

Will there be any extra charges for me to pay if I purchase a Voima from outside of Finland?

All Voima orders placed by customers within the EU will be charged the correct VAT amount as set out within their region. The amount of VAT will be displayed and added to the order in the cart when purchasing. All orders placed outside of the EU, will not be charged VAT. However, you will be responsible for paying all relevant VAT and duties when the order arrives in the destination country. This varies from region to region, so it is best to check your local governmental guidelines for the most up-to-date information.
