How do I get additional locks sharing the same key as the battery?

On all Shimano powered Bike43s you can order additional locks sharing the same key as the battery. Simply give the Abus YourPlus key number from the battery to your dealer, and order from him either of those:

  • frame lock Abus 5750LNR Plus (art. 79736 EAN 4003318797361). An optional chain is available : ACH 6KS/130 BK
  • U-lock Abus Granit 470/150HB300 (without EaZy KF because the frame already holds the lock while riding)
  • foldable lock ABUS Bordo 6015/90.

About 2 weeks later you will be able to pick them up from your bike store.

Life time warranty

We are so sure about the quality of our design and materials that we give a life time warranty on Bike43 frames for bikes purchased in Bike43 official dealer network. It is provided to original owners only (not transferable) for normal usage of the bicycle (professional usage is not covered by this warranty).

Which motor to choose?

The key concept is that the slower you like to pedal, the more torque you need from the motor.

From within our range, here are the different offers:

  • Performance series : The Shimano E6100 offers 60Nm of torque, and is matched with the brand new superb Nexus Inter5E for ebikes. Shifting under load is possible, and of course at stand still too, unlike a cheaper derailler system. The E6100 is able to operate the Di2 electronic shifter in manual or fully automatic mode. The automatic mode guarantees that the motor is always revving fast enough to deliver power. This drivetrain is the most advanced system on the market, it is lightweight, energy efficient for maximum battery range and robust. The Bike43 Performance series will cover the needs of all users.
  • Alpster series : For those living in mountain areas, or preferring to pedal at a lower cadence, or wanting ultimate performance and good vibes we recommend the Alpster series fitted with the Bosch Cargo Line – 85Nm.

What is the weight distribution the Bike43?

The weight distribution on the wheels is 50/50 with only the rider, and 40% (Front) / 60% (rear) with heavy children. It’s way more balanced than a boxbike, and even better than a regular bike. The benefit is that the grip of both tyres is used in an optimum manner for braking and for speed in the corners. It’s easy to ride, and if you want to ride actively you’ll enjoy a great feeling of confidence.

How long is it?

The total length is 197cm, which is 5 to 15cm longer than a normal ebike. The wheelbase is 141cm. It will fit in any constrained size environment just as a normal bike.

The length of the bike is the minimum achievable while complying with the mandatory children seat installation, according to the EN14344 safety standard.

In combination with the footbox which allows the children to seat as much forward as possible, the length of the carrier is enough to allow both seats to be installed complying with the EN14344 §14.2.5a, as shown below.

Why do make the kickstand yourself?

It’s correct, we don’t buy an off-the-shelf kickstand and bolt it under the frame. We do our own.

As users, we noticed that the stability of the bike for loading and unloading is extremely important on a daily basis. We couldn’t reach this goal with standard products, they were just too weak. Our kickstand has a wide spacing on the frame and on the ground.

Also, it has the exact correct length such that it’s easy to fold and deploy even with 60kg of load. You don’t have to lift the bike to fold or deploy the kickstand, you simply push the bike forward or rearward.

What is an Internal Gear Hub (IGH)?

An internal gear hub replaces a more basic regular derailleur. There is one chainwheel at the front and one cog at the rear. The chain never shifts, and never drops off. It’s kind of the goal because you would not like to experience this with your kids on board.

Second benefit, the gears are inside the sealed rear wheel hub, nicely lubricated and protected from the dirt and sand. There is no maintenance and it’s trouble free. The internal gears are made of steel and will normally last the life of the bike. As opposed to a regular cassette which has to be changed regularly together with the chain.

An Internal Gear Hub is the low maintenance and no worry solution for intensive usage.

Third benefit, you can change gears when stopped. If you’re surprised by a traffic light going to red, you can change back to 1st when standing still.

Fouth benefit, you can change several gears at once.

Fifth benefit, the cost over time is very low, as the sprockets of an IGH are in steel and the chain tension is pretty constant, therefore the chain will last 8000-10000km and the sprockets 20000km. On a cheaper derailleur solution such as used on competitors products the cassette & chain will last 1500km. The replacement will cost about 140€. In about a year the cost of an IGH is exceeded by the maintenance costs of a derailleur, and your ride experience will remain fantastic. From our experience, switching from a derailleur to an Internal Gear Hub is like switching from a B&W TV to a color TV. You don’t go back. It’s a no brainer for low maintenance and high mileage bikes.

Why a small rear wheel and larger front wheel?

The rear load had to be low for stability reasons, that was a hard point. Going for a 20” rear wheel was a no brainer.

In an urban environment the front wheel has to be able to go over kerbs, then it could not be 20”, it had to be bigger. 26” was cumbersome, and after much testing we decided to go for 24” as being enough for a smooth and comfortable ride, yet manoeuvrable. A bigger front wheel, for instance 24″ compared to 20″, offers more grip, thus better braking and more safety.

If you’re a dynamic rider, even very dynamic, don’t be afraid to go out of the footsteps: see how we are committed to test for you. Imagine how easy it will be in the city. Still willing a 20″ in the front? Nah!

Basically we’ve invented the modern longtail bike segment with the combination of a 24” front and 20” rear wheels.

Recently, such a layout is increasingly popular on the MTB scene, they are called mullet bikes.

Steel frame, not aluminum alloy, really?

Oh Yesss! The development team made their teeth on high performance race cars, like Le Mans LMP1 racers of 700BHP traveling in the Mulsanne straight at 330km/h and taking high speed corners under 3.5 lateral g’s. And they do so for 24 hours in a row. Extremely harsh conditions, and such an amazing school! Guess what, the frame of the Bike43 is made of the same grade of steel as the suspension parts of those cars, the proven high performance SAE 4130 (chromium and molybdenum alloyed steel). No need to say that those parts need to be both strong and lightweight.

Your benefit is that such steel will not crack from fatigue failure, as opposed to aluminum. As an example, most world touring bikes (remember the pics of those bikes heavily loaded in the beautiful landscapes of Mongolia) are made of this refined CrMo steel.

Steel also offers an unbeatable comfort, because the material itself absorbs the roughness of the road better than aluminum alloys. It’s a physical fact.

Don’t be confused with regular steel used for low cost and children bike. The CrMo steel is twice as strong, therefore two times less material can be used, and a construction will weight half the weight. On the frame of a Bike43 the weight penalty of CrMo steel vs aluminum alloy is minimal, around 1kg. It’s the weight of your drinking bottle. Trust us, on such a transport bike it makes no difference at all. But all the benefits will matter to you.

CrMo steel is the choice of the connoisseurs.

Using the bike

How much can I carry on my Bike43?

  • The maximum gross weight is 200kg, this includes the bike’s own weight.
  • The total weight of the rider and cargo is 170kg.
  • The maximum weight for the rider is 100kg, more is possible on request.
  • The maximum load on the rear carrier is 100kg.

Does the Bike43 fit in a bicycle parking?

As for solutions implemented in Belgium it’s just fine. The Bike43 fits in a Velo-Boxx just a standard bike. Even with the Roller Coaster installed.

We’d love to hear your feedback about other popular bicycle parking solutions.

Important note : The most recent model of Velo-Boxx is currently not suitable for a Bike43

Can I carry a baby in a Maxi Cosi with a Bike43?

Steco are making a Maxi Cosi adaptor for bikes. They recommend it for babies starting from 4 months, and the device is compatible with those brands. The installation manual is available on the same page. There is basic integrated suspension system but remember to ride gently.

One more seat remains available in front.
