What Wallke is
Wallke sells folding fat-tire e-bikes from wallkeebike.com. The H9 series page describes full-suspension folding bikes with fat tires, a color display, and either one rear motor or two hub motors. Support on the warranty page is sales@wallkeebike.com and +1 646 502 7256, with online coverage listed Monday through Friday, 5:00 p.m. to 2:00 a.m. PST.
The same warranty page says the owner is responsible for their own riding, and that Wallke is not liable for accidents or injuries. That sentence is the company's liability line. It is not a safety test.
Which H9 configuration is which
On the H9 series table, the single-motor H9 Ultra lists a 2000W rear motor, 105 Nm, a 1920Wh battery, torque sensor, 4-piston hydraulic disc brakes, 20×4-inch tires, a listed weight of 132 pounds, and a 400-pound load. Charge time is 5–6 hours on a 48V 6A charger.
The H9 Ultra AWD column lists dual 1000W motors, 95 Nm plus 95 Nm, a 2640Wh battery, a torque sensor, dual-piston hydraulic discs, the same 20×4-inch tires, a listed weight of 147 pounds, and the same 400-pound load. Charge time is 8–10 hours, and the charger cell says "charging cable" rather than a numbered charger.
The H9 AWD column lists the same dual 1000W motors and 1920Wh as the single-motor battery size, a cadence sensor instead of torque, dual-piston brakes, 132 pounds, and a 5–6 hour charge on a 48V 6A charger. All three columns say 37 mph. Wallke's current H9 AWD page contains conflicting weight values in different sections of the same page — 108.03 lb, 119 lb, and 116 lb on the September 28, 2026 check — while its URL and title and the current 48V 40Ah battery lines also use inconsistent capacity naming. eBikeQuest therefore does not publish a standalone H9 AWD specification profile.
Battery and charging
The series table lists 1920Wh for the 40Ah-named single-motor and H9 AWD columns, and 2640Wh for the 55Ah H9 Ultra AWD column. Battery weight is listed at 18 pounds or 30 pounds in that same table. The page also mentions an energy-storage function on the Ultra AWD. This guide does not describe what devices that port can run, because the page does not give a tested output.
Wallke's battery warranty excludes a non-Wallke charger, a pack left empty for more than 30 days, storage below freezing or above 100°F, a broken seal, and water inside the pack. A capacity loss up to 30 percent in the first year or 500 cycles is called normal wear.
Where can you ride it?
A bike Wallke lists at 37 mph does not fit the Class 1, Class 2, or Class 3 speed caps used in Virginia and Maryland, and it is above the 20 mph motorized-bicycle cap in Washington, DC. Shared-use paths in this directory are written for class-legal e-bikes. Do not read a folding-bike product page as permission to ride an H9 on those paths.
Some Wallke marketing describes the bikes as commuters. The speed figure still controls the class question. If a display can be set to a lower limit, the bike's capability is what Virginia and Maryland look at when a speed limiter is changed, and the label has to match. This guide did not confirm a locked class mode on the H9 pages that were read in full.
Start with the class guide and the three law pages, then the trail directory, if the bike you actually buy is a class-legal e-bike. The H9 figures cited here are not that bike.
What to know before ordering
Match the battery's watt-hour label to the configuration you think you bought. The H9 names overlap, and Wallke's pages do not keep one battery figure per name. Ask which sensor you are getting, torque or cadence, because the series table splits them by column.
The one-year warranty replaces parts. It does not pay a shop. File shipping damage within seven days and keep the packaging. Warranty email is sales@wallkeebike.com, with the order ID and photos or video. The 37 mph listing is a class question. The dated regulator check is separate and is not a clearance.
