      Fiido D4s ebike purchased from Vive Scooters uk

      Excellent bike. Solid. Be nice to have some suspension on the bike but the service from Vive Scooters to get it to me on the promised delivery date was exemplary and much appreciated.
      I can highly recommend Vive Scooters and the e bike for its price to performance ratio is 5 punches above its cost IMHO and is a great starter bike

      Good value but far from perfect

      Be sure to read this honest review before buying. The Positives: Good value, Relatively light, Good size battery, Some parts are reasonable quality, Rides smoothly. Negatives:
      Contrary to what you may read online you can’t remove speed restriction! No torque sensor so power delivery is not smooth, Poor quality brakes, QC process is non existent/ bikes are not transported with care, Mine came with bent front fork brake mount meaning the front wheel wouldn’t move as the wheel was held solid by the front brake that was mounted at the wrong angle.
      The hanger the rear derailleur bolts onto had also be whacked meaning the chain made an awful noise due to it not running straight.
      The front brake rotor had been damaged and was badly warped and had to be replaced.
      Weak motor, not very torquey, Wire management is poor, Battery not removable
      No easy way of removing rear wheel if you had a puncture. Vive customer service: Excellent fast delivery of bike. They sent me out replacement parts quickly to try and resolve the issue with not being able to derestrict bike, however a replacement controller made no difference, and now they are just ignoring my emails which is frustrating. I wish I didn’t buy the bike now if I’m being honest.

      Fiido D4S Folding Electric Bike

      Ian venables

      My bike arrived and unpacked and assembled.very pleased with apperance. Been out for my first ride today and getting used to the gears and power mode..
      I'm well pleased with the bike and its good value for the money.

      Great Electric Bike

      For a number of years i already had a folding electric bike, and my husband had a mountain bike... but recently osteoarthritis crept in to my husbands knees and he was having trouble cycling up hills so we decided to get him a bike similar to mine and we chose the Fiido D4S folding electric bike.
      It was easy to assemble as there was actually little to do, the most fiddly part was putting the mudguards on but we had had them given free as part of the deal so that was great.
      After charging the half full battery we took the bike out for it's maiden voyage, and it is great! Easy to ride, easy to set handlebar and seat height.... comfortable even with no suspension... and powerful!
      Both of our bikes fold small enough to get them in our car, which is great as i have no desire to start adding bike racks to my car.
      We haven't explored far enough yet to know how many miles we get from it, but it's going to be enough. Very impressed with the bike for the price, and would highly recommend it.
