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.

Tern

Pros

  • One maker covers cargo, commuter and folding, so a household can run a cargo bike, a commuter and a folder without changing brands.
  • The cargo bike pairs a battery of 1,600 Wh with a claimed range of 288 km, driven by a bosch motor.
  • A payload of 210 kg on that cargo bike carries shopping and school kit in a single trip.

Cons

  • The lightest bike listed is 22.8 kg, so stairs and platform lifts work against these machines.
  • Buying runs through dealers, dealer, so the entry price is set shop by shop rather than by the maker.
  • Servicing is handled by a partner network, so a repair depends on which partner covers your area.

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.

Tern

Who it suits

  • Households that need a payload, since the cargo bike is rated to 210 kg for shopping and children in one trip.
  • Riders who want the drive in the frame rather than a wheel, with listed placement of mid on a bosch unit.
  • Daily riders who want hydraulic braking, since brakes listed for the range are hydraulic disc.

Who should look elsewhere

  • Riders after fat tyre or eMTB shapes, where HK Beirui Trade Co. covers fat-tire and eMTB through commuter, folding and fat tire and Tern lists cargo, commuter and folding.
  • Buyers wanting city, hybrid and step-through frames, which Kalkhoff lists in city, hybrid and step through while Tern's range is cargo, commuter and folding.
  • Riders on town and step-through trips rather than loads, since iSinwheel's commuter, city and step through adds city, step-through and eMTB alongside commuter and folding.
