CONs of ESPIN 21 NERO All Terrain E-Bike:

  • The details of the stem and headset are not available in the vendor’s specifications, so I can’t conclude that they are adjustable?
  • It is not known if the tires protect against punctures because of a poor specification label.
  • ESPIN BIKES can only buy online, so there is a risk about delivery damage.
  • ESPIN BIKES are not partners with local dealerships to sell and maintain e-bikes, so you should contact the seller directly for any concerns.
  • The fat tire rolling on the hard pavement is surely very noisy, but good for riding on the bumpy road.

The overall ratings of ESPIN 21 NERO All Terrain E-Bike:

Reviewed by the ESPIN BIKES certified buyer, Roberto Corpuz on 28 June 2021 – The overall ratings are 5.0 out of 5.0:

For over three months now, I’ve tested the Nero around the many steep and scenic hills of San Francisco such as Pacific Heights, Russian Hill & Golden Gate Heights. All were easily climbed with the well equipped motor and pedal assist.

In comparison to a number of similarly configured 750W fat tire bikes that I’ve ridden, none is as powerful as the Nero.

With the sturdy front & rear racks, grocery shopping & other errands can easily be done without having to rely on a car or public transportation. Exercise & fresh air instead of stagnation & pollution!

For price, utility, power and overall value in its class, the Espin Nero is numero UNO!

Our Opinions:

  • Obviously the buyer stayed in California, it is convenient for him to purchase from the ESPIN BIKES.
  • For a 750W engine with a torque of 85 Nm is certainly powerful to flatten out any steep hills and go for speed if you like it.
  • I have read all 41 reviews, I find no complaints about the flat tire body so CST tires must have good protection against the flat tire.
  • There is a complaint about the delayed delivery and the buyer’s review did not show full so not sure what is the underlying cause.
  • The overall value of the ESPIN 21 NERO is proven by its powerful, utility, and comfortable to ride.

Reviewed by the ESPIN BIKES certified buyer, Lee Herendeen on 15 March 2021 – The overall ratings are 5.0 out of 5.0:

We live in the hills and now I can cut through residential neighborhoods thru a shortcut and be at Starbucks in 6 minutes!!

My wife and I spent 3 great hours riding from Palos Verdes to Manhattan Beach, had lunch and back this weekend. It was awesome. Never inhibited time go on a bike ride now. Also great on horse trails! So glad we bought these.

Our Opinions:

  • ESPIN 21 NERO is the all-terrain e-bike, so you can ride in any terrain for you to explore many locations that you have never been there.
  • The buyer has never said a word about the e-bike but you can see clearly that this is a life that changes for the buyer and his family.
  • If you believe that UPS or FedEx is safe to deliver the new electric bicycle since we know that the seller paid the carrier $175 for quality delivery.

  1. Hi Stephen. Thank you for another great review. Summer is here and electric bike is great option fo family trips. I was looking for one for a while but its not easy to choose with so many options on market. But looking on your review Espin seems as a great choice. It has good specification, I like the design and price is really reasonable. Looking forward to test it in practice.

    • You are welcome to visit us again with your valuable comments. May God bless you to find your dream bikes sooner. 

      It is truly hard to decide when you want to purchase an e-bike online. If delivery, quality of UPS or FedEx cannot be improved, it is a big impact for sellers to sell online. COVID 19 has pushed up a lot of the delivery service, and I wish some new transporter can deliver the new e-bike safely for every buyer.

      Thanks for your visited again and wish you get your dream e-bike

  3. I’ve been looking for an e-bike to cut down on commute time for a reasonable price. The Espin 21 Nero seems like a good option. The 750W motor and 50 miles per charge is very appealing. I’m a little concerned about getting a fat tire though. I’ve never tried that before and don’t know if it will be annoyingly loud to ride. Anyone with experience?

    • Hi Miss Momo, you do not need a fat tire e-bike since it is quite noisy when riding on the hard pavement road. 

      If your need for an electric bike is to cut down the commuting cost, you can consider this BUZZ bike, slightly cheaper but higher spec with the mid-drive motor. And the tire is 3″ width still a better all terrain tire, but less noise due to the thread is a fast rolling type. https://bestaffordableelectric

      You are welcome to ask any question related to the BUZZ bike at your convenient time. Thank you for your visit and
