Booda Bike Alpine – 3x3 electric shifter - M

You can pay via bank transfer or credit card.

Low maintenance is a core design goal. The 3X3 internal gear hub is sealed, so there is no derailleur to adjust. The Gates CDX carbon belt does not need lubrication and does not rust. The hydraulic disc brakes are one of the lowest-maintenance braking solutions available, and the Schwalbe G-One Allround tyres are tubeless-ready and supplied with Effetto Mariposa Végétalex sealant. All Booda Bike models use standard components, so any general bike shop should be able to service them.

It uses the 3X3 NINE internal gear hub made by 3X3 (H+B Hightech GmbH), fitted in the rear wheel: 9 speeds and, according to the manufacturer, a 554% gear range. You shift with the buttons in the TRP Hywave brake levers: the levers send the command wirelessly via Bluetooth to the shift unit on the hub, which is powered by a power bank. The TRP SW-C8020E bar-end unit, which connects the Hywave levers to the 3X3 system, is part of the Hywave set on this bike.

Yes. The electronic shift unit on the hub is powered by an external power bank, and the standard model comes without one. The power bank fits in the Apidura top tube pack that comes with the bike. The handlebar trigger runs on its own batteries.

Yes. The Alpine 3x3 is an early bird product with electronic shifting powered by a power bank in the top tube pack. The solution was developed in agreement with the hub manufacturer, 3X3.

Yes. It has a Gates CDX carbon belt drive. The belt is clean and quiet, does not need lubrication and does not rust. The belt tension is set when the bike is assembled and normally does not need adjusting later; the frame has an eccentric bottom bracket designed by Booda Bike, and if its bearings wear out they can be replaced without touching the belt tension.

The drivetrain has few wearing parts: a sealed hub, a belt that needs no lubrication and no derailleur or cassette. The frame is steel, which dampens vibrations, and the fork is carbon. The steel frame tubes are protected against rust with an internal coating, and the bike has a 3-year warranty. The maximum load is 120 kg; the bike can carry more, but only if you reduce the dynamics of riding.

Yes. The Alpine was designed for long tours and rougher terrain, and an internal gear hub with a belt drive keeps the drivetrain clean in everyday use too. Remember that the electronic shifting needs a charged power bank.

No. The standard model comes without a lighting set.

The Alpine comes in S (rider height 155–170 cm), M (170–185 cm) and L (185–200 cm). The seat tube is 530, 560 and 590 mm, and the reach is 381, 381 and 398 mm respectively. The full geometry table is above.

The maximum tyre size is 40 mm. The Schwalbe G-One Allround 622x40 tubeless tyre fits this build perfectly; bigger tyres would touch the frame if the wheel is slightly out of true. A 40 mm tyre also fits with mudguards, as long as you do not use mudguard lighting.

All three are belt-driven gravel bikes with the same Alpine frame. The Alpine 3x3 has a 3X3 internal gear hub with electronic TRP Hywave shifting. The Alpine Rohloff has a Rohloff Speedhub 500/14 shifted by cable with Shimano GRX levers. The Alpine e-14 has a Rohloff Speedhub 500/14 with Rohloff E-14 2.0 electric shifting and TRP Hywire levers.

We ship the bike as assembled as possible. You only have to fit the handlebar (stem, 4 mm Allen key), the front wheel (6 mm Allen key), the seatpost with the saddle (4 mm Allen key) and the pedals (6 mm Allen key).

First press a shift button and watch the light at the handlebar end: green flashing means the shifter works, no light means its battery needs replacing. Then connect to the bike with the official 3x3 app. If the app cannot find the bike, the shift unit has no power, most often because of a faulty USB-C cable to the power bank. Contact us with the error code or a screenshot from the app if the problem remains.

Not yet, but we’re working on it! :)

If the bike isn’t what you expected, you can return it within 14 days. Please make sure to pack it carefully so it arrives back to us in good condition. You can find the return conditions in our Terms and Conditions.

All our bikes are made using standard components, so they’re easy to maintain. This is a core principle across all our models. Thanks to this, any general bike shop should be able to service your Booda Bike.

This depends on the model and configuration, but most maintenance and assembly can be done with these tools: 4 mm Allen key, 5 mm Allen key, 6 mm Allen key, and a T25 Torx key.

Once you select your country, all prices will be shown with the applicable local VAT included.

Currently, we operate as an online-only store, but we’re working on making test rides possible in the near future.

Once we receive your order, we begin processing it. If all parts are in stock, our team will prepare the components in the order in which the orders were received. If something is out of stock, we’ll check the expected arrival or order it immediately. After that, your bike enters the assembly phase, which usually takes 1–2 business days. Once the bike is built, it undergoes a thorough quality check to ensure everything is assembled correctly. Then it gets packed and shipped straight to your door.

If you bought your bike through our website, just go to the “My Bicycle” tab in your profile — there you’ll find all components specific to your bike, so you’ll know exactly what you need and can easily reorder.

The customization options on our website are based on what we've learned actually make sense over the years. There are very few modifications we are both able and willing to make that aren’t listed online — but feel free to email us at info@boodabike.com and we’ll be happy to discuss it.
