Our verdict on each
A DECE OASIS
A DECE OASIS suits riders who want folding, city and cargo bikes from a single maker, and who live in the European markets listed for delivery. Entry prices start at €1,199, the frame warranty runs 5 years, and support runs on email and help centre only.
Riese & Müller
Riese & Müller suits riders who want a belt-driven, Bosch-powered commuter built to be serviced rather than replaced, and who will buy from a dealer rather than online. The 5 years frame warranty carries the trust case, the entry price does not.

Pros and cons
A DECE OASIS
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.
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.
Riese & Müller
Pros
- Bosch mid motor in mid position, the layout most e-bike service workshops already handle
- Belt drive and a removable battery cut the parts that normally wear first on a commuter
- 5 years on the frame, longer than the 2 years on the battery
Cons
- Support runs on help centre alone, with no phone line or live chat listed
- Sales run through a dealer model, so there is no direct route to buy around the shop markup
- 27.7 kg for the lightest bike is heavy for a stairwell or a train platform
Who each suits
A DECE OASIS
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.
Riese & Müller
Who it suits
- Commuters covering a long daily distance on a bike they plan to keep for years
- Households replacing an unreliable bike once and wanting belt drive instead of a chain
- Riders who prefer a dealer purchase with a local workshop on hand
Who should look elsewhere
- Buyers wanting the lowest entry price in the €8.73 to €7,774.27 spread of listed e-bikes
- Riders who need phone or chat support, since help centre lists a help centre only
- People who plan to lift a bike into a flat or a train, given 27.7 kg

Questions about each
A DECE OASIS
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.
Riese & Müller
How much does a Riese & Müller e-bike cost?+
Entry prices for listed e-bikes start at €8.73 and run to €7,774.27, with €876.09 as the middle. The bikes themselves are sold through a dealer model, so the figure on a dealer's list is what you pay rather than a website checkout.
Why do these bikes cost more than other e-bikes?+
Part of the premium buys a Bosch motor in mid position rather than a hub motor, which is the less common layout among listed brands. Part buys belt drive, which is a higher-cost build than a chain. The rest is dealer servicing and a 5 years frame warranty.
