You can test ride TST e-bikes at the TST EBike location at 1081 Grand Ave, Diamond Bar, CA 91765, with local pickup and product support available at that address; the warehouse is open for pickup and inspection Monday through Friday, and the best way to schedule a visit is to contact TST EBike support first with the model you want to try. This page is the practical guide to what to expect, what to bring, and how to get there.
The Diamond Bar Location and Its Address
The Diamond Bar address is 1081 Grand Ave, Diamond Bar, CA 91765, part of the TST EBike California operation alongside the Ontario warehouse. The location serves the San Gabriel Valley and eastern Los Angeles County, and it is the designated pickup and inspection point for buyers in that area.
Before driving out, confirm the visit with TST EBike support, because the location is a warehouse operation with pickup hours rather than a walk-in retail store, and the staff can confirm the model availability and the exact entry point.
Models Available to See and Test at the Warehouse
The warehouse keeps its demo selection aligned with the most popular models, so availability tends to favor the R002, R7, and R9, with the Carrier, Surfer, and Buddy Pro available on request; the GT63 off-road machine is usually available for a supervised test in a suitable area. Because stock rotates, the confirmation call is what guarantees the model you want is on site. If the exact model is not available, the staff can usually show the closest alternative so you can check the fit and size characteristics that matter most.
The TST lineup available through the California operation includes the R002 moped-style bike, the R7 step-through cargo bike, the R9 dual-battery long-range bike, the Carrier cargo model, the Surfer step-through commuter, the Buddy Pro folding bike, and the GT63 off-road machine. Availability varies by stock, so ask support which models are on hand before your visit.
Seeing the bike in person is the best way to check standover height, seat adjustment, and overall size, because no spec sheet replaces a test ride for fit.
What Should You Bring to a Test Ride or Pickup?
One more item belongs in the kit: a phone with your route saved, because the test ride should include the kind of road you will actually ride, not just the warehouse lot. If your commute has a hill, find one near the warehouse; if you carry cargo, bring a loaded backpack. The closer the test ride matches your daily route, the more useful the decision, and the warehouse staff can point out a suitable test loop nearby.
Bring a valid ID, the order number if you are picking up a purchase, comfortable shoes suitable for pedaling, and any accessories you plan to use with the bike, such as a helmet, lock, and phone mount, so you can test the real setup. If you are a new rider, bring a helmet even if the bike will be used off-road, because the first ride should always be protected.
Wear clothing you can ride in, and be ready to spend 30-60 minutes checking fit, handling, and the specific features that matter for your route.
The Five Things to Test on a Test Ride
| Test item | What it reveals |
|---|---|
| Mount and dismount | Frame height and step-over ease |
| Seat and bar fit | Ride position comfort |
| Brake feel | Stopping confidence |
| Assist and throttle | Acceleration behavior |
| Fold cycle (folders) | Hinge feel and stored size |
Bring your normal riding gear and take the bike through a start-and-stop sequence, a short climb if the area allows, and a brake test from riding speed, because those three moments reveal how the bike will feel on a real commute. For a folding model like the Buddy Pro, ask to see the fold-and-unfold cycle, because the hinge feel and folded size are the reasons to buy a folder. For a cargo model, load the bike with whatever weight you can bring, because the loaded ride is the ride you will actually do.
Use the test ride to check the four things that decide ownership: mounting and dismounting ease, seat and handlebar fit, braking feel at walking and riding speed, and the bike's weight when stopped. Then test the assist levels and throttle to feel how the bike accelerates, because the difference between assist modes is something a spec sheet cannot describe.
For cargo models like the R7 or Carrier, ask whether a loaded test is possible, because the bike's behavior with cargo is different from its behavior solo, and that difference is exactly why cargo buyers should test loaded.
Getting to the Diamond Bar Location by Freeway
The drive is straightforward from most of the San Gabriel Valley: Grand Ave connects to the 57 and 60 freeways, and the warehouse complex has parking on site, so the visit is practical for buyers from Los Angeles, Pomona, and the surrounding cities. Plan the appointment for mid-morning or mid-afternoon to avoid the worst traffic, and confirm the exact building with support before leaving, because warehouse complexes can have multiple entries. If you are coming from farther away, combine the test ride with an order pickup to make the trip count.
The Grand Ave address is accessible from the 57 and 60 freeways, with parking at the location; use the exact address in your navigation app and confirm the entry with support, because warehouse complexes often have multiple buildings. If you are coming from Los Angeles or Orange County, plan for traffic and confirm the visit time with staff before leaving.
The Diamond Bar location serves as the pickup and support point for buyers who choose local pickup instead of delivery, so the same visit can combine a test ride with an order pickup.
What If You Cannot Visit the Warehouse in Person?
If you cannot visit Diamond Bar, TST EBike ships bikes from its California warehouses in 3-5 business days, and the support team can walk you through assembly over the phone or email. The delivery process and what to expect are covered in the shipping guide in this series, including the assembly checklist for first-time buyers.
The test ride remains the better option when possible, because fit is the one thing that cannot be verified from a spec sheet.
Combining a Test Ride with Local Pickup
Buyers who choose local pickup can combine the visit with a test ride: confirm the order, schedule the pickup, and use the same visit to test the exact model before taking delivery. The inspection checklist at pickup covers the frame, battery, charger, and accessories, and the staff can answer setup questions on the spot.
Combining the two trips saves a drive and gives the buyer the confidence of testing the exact unit they are taking home.
Conclusion: Schedule the Visit, Bring the Basics, Test the Fit
The test ride is the deciding step, and the Diamond Bar visit is where it happens.
Test rides are available at the TST EBike Diamond Bar location at 1081 Grand Ave, Diamond Bar, CA 91765, by appointment through support. Bring an ID and a helmet, test fit, brakes, and assist feel, and combine the visit with a local pickup when possible.
