Pros and cons
Pros
- Belt drive and a removable battery come as standard, a pairing that suits riders who would rather stop oiling chains on a bike kept in a hallway.
- Frame warranty of 5 years with 2 years on the battery.
- Hydraulic disc brakes across the line, hydraulic disc, which matters on wet city streets.
- A payload rating of 120 kg and a lightest bike of 14.7 kg cover shopping runs, stairs and trains.
Cons
- Support runs on email and help centre only, so a fault gets handled by email or the help centre and not by phone.
- Nominal power of 250 W sits at the floor of what the category lists, so steep routes mean more rider input.
- Repairs go through the brand's own service, own, which means returning the bike rather than visiting a nearby dealer.
- Delivery stops at the listed markets, AT, BE and BG, so riders outside Europe have no route to a bike.
Ready to try A DECE OASIS?
Scored 8.9 / 10 by CommuteCue.
Who it suits
- Riders who want folding, city and cargo bikes from a single maker, with 5 year frame cover on each.
- Households replacing a second car for short urban trips, who can send a bike back within 14 days if it does not suit.
- Buyers who want belt drive and a removable battery without giving up folding, a mix the city, hybrid and step through range at KALKHOFF does not include.
Who should look elsewhere
- Riders outside AT, BE and BG, since shipping is limited to the listed countries.
- Anyone who wants to sort a problem by phone, because email and help centre covers email and a help centre.
- Shoppers who want a long model list to browse, since the reference line is short and centred on a folding bike and larger wheeled versions.
What it does well
The range rests on a folding, city and cargo platform, with details that matter for a bike kept at home and at work. The battery is removable, so the pack charges indoors rather than in a hallway, and the largest battery in the range is 370 Wh. Claimed range is 100 km, which covers most urban commuting legs. Belt drive removes the chain oil that marks a commuter parked in a flat, and the lightest bike is 14.7 kg for stairs and trains. The payload rating of 120 kg puts shopping runs in scope. The frame is covered for 5 years and the battery for 2 years, returns run for 14 days, and finance is offered so the entry bike can be split into payments.
Pricing
Entry is set by the cheapest bike at €1,199, and the ceiling is €2,499. The spread between those two figures is where a folding commuter separates from a cargo frame, so a buyer can step up within the same maker rather than changing brand. The entry price covers the folding end of the line, and the top price covers the larger frames and load carriers.
Where it sits among rivals
On entry price, A DECE OASIS ranks 94 among 149 brands, so the cheapest bike sits well above the low end of the field rather than at the bargain end. On the top price, the placing is 79 of 145, a stronger position than at entry. The gap between the two placings is the part to read: the floor is priced above much of the field, while the ceiling holds its ground.

Frequently asked questions
How much do A DECE OASIS bikes cost?+
Prices start at €1,199 for the cheapest bike in the range and reach €2,499 at the top. The middle of the range covers the larger frames and the cargo options, so a commuter and a load carrier come from the same maker. The figure quoted is the price of the bike itself.
Which models are in the range?+
The reference line covers a folding bike, a larger wheeled model and two higher specification versions, so the range spans small frames and bigger wheels. The lightest bike is 14.7 kg, which counts if you carry it up stairs or onto a train, and the payload rating reaches 120 kg on the load carrying frames.
Which motor and assist class do the bikes use?+
The motor sits in the hub, hub, and comes from Bafang, bafang, with 250 W nominal power. The assist class is EU 25, the pedal assist limit for European road use, so the bikes are set up for commuting rather than for motorised speed.
What range can you get on a charge?+
The claimed range is 100 km, and the battery is removable so it can charge indoors instead of in a hallway. The largest battery in the range is 370 Wh, which sets the ceiling for that distance figure. Real distance moves with rider, load and hills.
Can I return a bike that does not suit?+
There is a money back window of 14 days, so a bike that does not fit the commute can go back inside that period. The battery being removable means the pack does not have to travel with the frame. A frame warranty of 5 years then covers the bike well past the return window.
What warranty comes with the bike?+
The frame is covered for 5 years and the battery for 2 years, so the frame outlives the pack it carries. The battery is removable, which means it can be replaced on its own rather than with a new frame. Keep the order details for any claim.
Where can I buy and service one of these bikes?+
Bikes are sold direct and through dealers, both, and finance is offered on the range. Repairs run through the brand's own service, own, so a faulty bike goes back to the maker rather than to a local workshop. Buying direct suits riders who know the model they want.
How do I get help when something goes wrong?+
Support runs on email and help centre, so questions go by email or through the help centre rather than by phone. The help centre suits quick questions about the removable battery or the belt drive, and the 5 year frame warranty sets out what a claim covers. Have the order details ready.
