With i:SY it is! The i:SY has a single-size frame. The perfectly conceived frame geometry makes it possible. The frame is adjustable in length when people between 150 and 190 cm tall sit on it. 

Thanks to the flat seat angle and the comparatively “long” top tube this is possible.
For people up to 210 cm our XXL models are ideal

If taking bags or the backpack along it is important to make sure that no carrying straps get caught in the pokes or in between guard and wheel. Most straps can be removed via karabiner. The shoulder straps of the backpack can be safely stowed away with the inbuilt clip buckle.

All bags and baskets that are delivered incl. a MonkeyLoad-T plate are also fitted with a lock. For our waterproof trunk bags that are fitted with the MonkeyLoad-S system we offer a separate anti-theft. MonkeyLoad-S lock, Art.No. 5020319. 

The reason lies in the safety connection. The MonkeyLoad-T plate has a maximum permissible load of 10 kg. The weight of the i:SY basket needs to be deducted from that as well.

It is possible in most cases. Our i:SY Front carrier with KLICKfix is compatible with all bags and baskets that have a KLICKfix plate, a BASIL KF or a MonkeyLoad adapter plate. For baskets or crates for the rear carrier we offer the MonkeyLoad-T plate. They can thus be fitted onto the i:SY rear carrier ML ready.

i:SY models from before 2022:

The fitted rear carrier is not approved for the usage of a child seat. The i:SY rear carrier ML, Art. No 23000105, can be retrofitted for this purpose.

i:SY models from 2022 and younger:

The fitted rear carrier is approved to the usage of a child seat.

Please note that the rear carrier has a width of 110mm. Not all child seats are suitable for this size. We recommend the Thule Yepp 2 Maxi Rack Mount, Art. No. 5021310.

Exceptions for model year 2024:

The SKYFLY S10 and SKYFLY E5 are not approved for taking a child along.

The rear carrier fitted onto our P12 models (Compact, XXL and CARGO) has a width of 120mm. All standard child seats are compatible.

NOTE: If using a suspension seat post children’s fingers might get trapped. To avoid this we offer a range of protective covers in our portfolio.

We highly recommend using one when a child rides along.

To protect the motor during transport, e.g. from grit, we offer a neoprene cover.

Caution: The cover needs to be removed before cycling! Danger of falling!

For the BOSCH battery 400, 500 and 545 Wh we offer neoprene covers as well. They can remain on the battery during cycling and provide a protection against grit. In lower temperatures the neoprene material extends the battery life.

The protective cover needs to be removed for charging.

We offer an adapter which enables a usage of all standard trailer couplings and therefore trailers in combination with our i:SY models.

The i:SY Trailer Adapter 1.0 is suitable for i:SY models from 2022 till 2024 (with BOSCH Motor and aluminium frame).

The i:SY Trailer Adapter 2.0 is suitable for all i:SY models from 2024 with PINION MGU; except i:SY CARGO.

NOTE: Our i:SY SKYFLY models made of carbon are not authorised for the use with a trailer. 

No. The gear ratio is adapted to smaller wheels.

No. The opposite is the case on the i:SY: thanks to the low centre of gravity, the i:SY can be handled extremely safely in difficult situations and on poor surfaces such as woodland tracks, gravel paths, sandy paths and cobblestones. And even high speeds, when riding downhill, for example, present no problem for the i:SY.

No. Simply put, wider tyres with a short contact surface rotate more easily than narrow tyres with a long contact surface. However, we use the balloon tyre principle at i:SY, minimising the air pressure to such an extent that, on the one hand, the rolling properties don't really deteriorate, but, on the other, we make purposeful use of the great ride comfort provided by the air suspension. We thus recommend using a tyre pressure of 2.0 to 2.5 bar on the front and 2.2 to 3.0 bar on the rear, depending on the user's weight. It is recommended to check and adjust the air pressure every four weeks as a minimum.

Yes, of course, you can also ride long distances on the i:SY. The sitting position is comfortable and the flow of power is excellent thanks to the flat seat angle. For this reason, you can also use the i:SY for both longer tours and cycling trips.

The i:SY has the wheelbase of a normal 28 inch wheel and the rear frame is also suitably long. You can thus easily attach large bags, such as the i:SY panniers or Ortlieb panniers. They are also far enough above the ground.

We at i:SY have consciously decided against a folding mechanism in the main frame. First of all, it weakens the structure in terms of stiffness and, secondly, a folded vehicle is considerably more difficult to handle. The weight is the same, but it can no longer be rolled along. You need to be very strong or a second person to stow it away whereas you can simply wheel an i:SY into many cars.

We think Bosch motors are an excellent choice, even for the long term. It's a long-established German company and has an excellent organisational structure.

Manufacturers and dealers receive training on a regular basis and are provided with perfect support. Every i:SY dealer can install the latest motor updates and the Bosch diagnostic software provides information about the entire system's functions during every inspection. Moreover, the Bosch system is very widely used and virtually every pedelec dealer in Europe is familiar with it.

As you might expect, this depends on a whole host of factors, starting with the rider's weight, the chosen level of assistance and, obviously, especially the selected trip distance. It makes an enormous difference whether the route is on flat or mountainous terrain. Wind is also a factor.
Tip: Use the power gauge and also the gear shift recommendations on the display. You'll increase your range as a result. And use the Reset button to reset the possible range displayed before each daily tour. It makes for carefree rides.

Bosch batteries are of very high quality. That's something you'll notice right from the outset. Low weight, high-quality cells, no self-discharge, fast charging times and a long service life. Assuming normal usage, a rechargeable battery is expected to perform well for a period of five years. After that, it is still a good secondary battery.

It depends on the capacity of the battery and which charger is used. Here is a little overview for you. Note: You can partially recharge at any time. It won't damage the battery.

i:SY models with BOSCH:

Yes, there is a socket on the left-hand side as you face the direction of travel. You can connect the charger to this socket.

Yes. Bosch can supply a test device that measures the battery's capacity and prints out a test report. Please ask your i:SY dealer if such a device is available.

The computer "remembers" your riding style and takes into account the distances you have ridden so far and the assistance you selected when calculating the range. Before each new tour, please reset the range with the reset button. The display will now show the maximum possible range again.

Different riders have different riding styles and consume different quantities of power. Simply reset the range now and again and the remaining ranges should match again.

Yes, they might if you don't provide adequate care. This is especially the case if you have been travelling with the vehicle on the coast and have come into contact with salt water or road salt in winter. All the attachment screws we use are made of V2A stainless steel. However, salt water is so aggressive that even stainless steel screws of this grade will rust. We recommend that you swill the vehicle with warm water and wash off the salt. The manufacturer uses steel in the brake discs, which are highly sensitive to salt. Brake discs can be cleaned with hot water or more effectively with brake disc cleaner. Wet parts are best dried with a cloth.

The LowRider is suitable for a maximum load of 4 kilogrammes per side. This is objectively much more than it might sound at first.

No. The belt sprockets and toothed belts are designed specifically for individual models.

Go to our dealer search and enter your town or city. It will display all i:SY specialist dealers in your area. Our i:SY Flagship-Stores are equipped with our entire range of products.¹ You might like to phone the i:SY specialist dealer concerned and check that the model you prefer is available for a test ride.

Our i:SY Flagship-Stores also show our range of accessories.¹

¹ subject to availability

The new pannier rack for model year 2022 onwards is approved for 27 kg and is now also suitable for carrying children.

Exceptions are our i:SY models made of carbon: the i:SY SKYFLY E5 and i:SY SKYFLY S10.

i:SY does not offer a retrofit kit for suspension forks. If you would like to ride an i:SY with a suspension fork we have two models - the i:SY S10 ADVENTURE and the i:SY E5 ADVENTURE - in our portfolio. 

Generally speaking a suspension fork can be retrofitted. But it is pretty complex. The alteration requires several new parts such as the suspension fork, a new front wheel, stem, handlebar, display holder as well as new brake lines and other parts. Unfortunately, we are not able to offer all these parts at a reasonable price.

Clean with a damp microfibre cloth, a cotton cloth or a fine brush in combination with a special Alcantara cleaner. Clean attachment parts by applying gentle pressure and using circular movements. Dab them with a damp cloth to finish off. Attachment parts can also be waterproofed to provide better protection.

Your i:SY dealer is your direct local contact and will be happy to help you. If any defects arise or any warranty claims are made, we will maintain close contact and dialogue with your dealer. Needless to say, you can also contact another i:SY dealer, but this will incur additional costs. We therefore recommend that you purchase an i:SY near you.
