This is my second time I am purchasing…
This is my second time I am purchasing a bike from HappyRun. So far it’s been two weeks from my purchase date and I still haven’t received my complete package. The bike comes in two shipments, one with the frame and wheels to the bike and the second with the other parts to the bike, like the second battery. I am still waiting for the second package. It is frustrating for the buyer not to have all parts for the bike. But I don’t know if it’s a HappyRun issue or a FedEx issue. FedEx has awful customer service, happy run has answered my emails within 24 hours. I appreciate that. Keep me informed. And if anything when delivering the bikes make sure all parts are delivered on the same day.

Dear Customer,
Thank you for sharing your experience and for your kind words about our customer support. We sincerely apologize for the frustration caused by the delay with the second package.
We completely understand that receiving the bike without all of the necessary parts, especially the second battery, is inconvenient. We also appreciate your understanding that the delay appears to be related to the carrier's delivery process rather than the product itself.
The package is currently at the Chino FedEx facility. We have also followed up with FedEx to help move the shipment along as quickly as possible.
If you would like to receive the package sooner, you may also contact FedEx at 1-800-463-3339 and request that the package be held at the Chino facility for pickup. Please have your tracking number and a government-issued photo ID ready.
We truly appreciate your patience and your continued trust in HappyRun, especially as this is your second purchase from us. We will continue monitoring the shipment and do our best to ensure you receive the remaining package as soon as possible.
Thank you again for your understanding and support.

Hi William Locken,
We’re very sorry to hear about the issues you experienced and we appreciate you sharing your feedback. We have already replied to your email and will continue assisting you there.
Regarding the chain issue, we can help reimburse the cost of the replacement chain. For the odometer concern, could you please send us a video showing the issue so our technical team can review it?
For the battery issue, could you please use a multimeter to check the battery voltage and send us the result? If our engineers confirm that the battery is defective, we will arrange a replacement battery for you.

I ordered my E-Bike on 4-27-25
I ordered my E-Bike on 4-27-25, and it arrived on 5-1-25, good delivery time. I could give Happyrun a 4 Star for the 2025 NEW HappyRun G70 2000W Dual Battery Fast Electric Cargo Bike. It runs great!
The 3 star is for the not so great customer support. I use the chat feature on HappyRuns website. I leave a message USA during the day and they will respond around 2 am my time, every time. So yes they are overseas.
Let me be clear, I Love the bike, the power, the distance. Able to ride in the bike lane and pass all bumper-to-bumper traffic. Thanks to dual batteries I can go a long way.
Con: The seat is not adjustable, so if you need to use pedal assist. You're too low. I am 5-10 and my knees are at the same level as the seat. Peddling up a steep climb is a total pain!! However, if you just use pedal assist on a normal level road, it is not as bad, yet it could still use an adjustable seat. The pedal assist works very well, and you really pick up speed fast! It can help you stretch out battery life.
Recap: Love the bike! Hate the pedal assist, and customer support is not that great.... Please read the One-Star Reviews to see what I mean.
E-Bikes! Have Fun, be Safe!!

Terrible quality, heavy components are supposed to be durable but they break easily
Got a flat that made the bike impossible to move any distance without becoming exhausted. Probably my fault due to not putting the spacer in but the front wheel doesn't roll well with it and that's that one of the reviewers ended up doing during assembly. Then it got stolen when I came back for it. That part isn't exactly the fault of Happyrun, of course, but I will fault them for making the bike so cumbersome to move in this circumstance. The thing is, it's a great bike (especially for the price) if you know what you're doing with respect to being a bike mechanic, but it's very easy to run into problems if you're an amateur like I imagine the target market is. Be warned!
