on the ball

From day one when I ordered a eahora romeo 2 2025 off grid lux has been in constant contact . From shipping the bike to after care I haven't had issues at all . They even called me to check on an issue I had and I actually spoke to a person , who was great by the way . Customer service has fallen to the big internet conglomerates but I didn't feel that way with the purchase , they have really tried to take care of me and answered every question I've asked , even ones that are stated on the site . Im happy I went with them .I hope I can purchase other stuff in the future here .
The products won't be flawless but their customer service is . Thanks again Greg

Damaged upon arrival, stellar customer service

Mototec Raider, paid for assembly, arrived with flat tire, dangling cracked headlight, scratched and scuffed. Customer service very responsive and able to resolve issues and make it right. They answer the phone and actually talk to you!

Extra battery for Ecotric Leopard

I bought an extra battery to increase my ebike range. Of all the sites I looked at, I was sure this one would fit my battery mount because it was labeled correctly. Not true of other sites. They shipped quickly and the battery was packed properly. Good business--would easily buy from this site again.

Excellent customer service

The whole process from ordering through receipt with Off Grid Lux was seamless. They responded quickly to our initial questions and helped us decide on the best product to suit our needs. There was a small hiccup with the shipment delivery (the fault of the carrier) and Odd Grid Lux contacted the carrier immediately and had our issue resolved. We researched many vendors before deciding on Off Grid Lux and their pricing and customer service cannot be beat.

This bike gave me a rush when I first rode it. Everything about it is completely unmatched. Drive one and you'll get a rush too.

Battery works and lasts a long time!

I bought this battery to replace my battery that died in my Ecotric 20810 (the fat tire one from around 2019 timeframe). Went on a 2+ hour ride and still had plenty of juice to spare. Wish it was cheaper but....it's a big battery and that's the retail price I guess.

Rockstar Customer Service

Ordered four inverters for a customer whose solar system was damaged by a utility surge. OffGridLux advertised these inverters at $2500. Upon ordering the inverters I was assured they were in stock and would be delivered. The next day I received a refund and the price of the inverters went up from $2500 to $3100 on the OffGridLux website. Chris in customer service explained the inverters were a new product and the $2500 price was added by mistake and the real price was $3100. He also told me his warehouse made a mistake they only had 2 of the 4 available. After expressing my frustration at the situation since the customer was already quoted the lower price, Chris worked out a deal and gave us the inverters at cost to OffGridLux for $2850 instead of $3100. Chris promptly adjusted the charge and made sure the 2 inverters were shipped out asap. As a small business owner I understand how small mistakes can be costly and sometimes the little things are the biggest problem. In good fashion Chris represented OffGridLux and my interests by communicating and figuring out an amicable solution for all parties involved. Thank you again Chris. You sir a true asset to your company.

Nice bike love the looks not as powerful as my pro 2 as one might expect but overall nice bike i did take it on a 47 mile trip and still had 50.1 percent left when i got home so no need to worry about a battery the best part of this bike is the company that sold it. I've been so impressed with this company which is why i purchased my 2nd bike from them they are nothing short of exceptional buy with confidence they are with your every step of the way and very fast to respond to emails and help with any problem ive come across i wish they sold other bikes just so i could buy from them off the grid lux is by far my favorite store keep it up guys I'll keep looking to see what you stock next
