Long-range everyday capability

EK7 built to make every mile easier

A comfortable step-through design combining a high-capacity removable battery, strong rear-hub performance and practical commuter equipment. The adjustable fit, front suspension, seven-speed transmission and large rear rack make it ready for daily transportation and relaxed weekend routes.

Strong, efficient assistance

A 750W rear-hub motor reaches 1000W at peak and is paired with five assistance levels, a twist throttle and an 82 N·m published torque rating. The standard speed setting is listed at 20 mph and can be adjusted up to the published 28 mph maximum where permitted.

01 / DRIVE

750W rated, 1000W peak

Brushless rear-hub power supports confident starts and everyday hills. Peak output describes a short-duration maximum and should not be confused with the normal operating rating.

02 / CONTROL

Five assistance levels

Select the amount of motor support to balance effort, pace and energy use. A speed sensor manages assistance, while a twist throttle provides motor control where local rules allow it.

03 / TRANSMISSION

Seven mechanical speeds

Seven selectable gears help match pedaling effort to starts, climbs and level roads. Shift one step at a time while reducing pressure on the pedals for smoother operation.

High-capacity removable power

The 48V 25Ah lithium-ion battery stores approximately 1200Wh. It can be removed for convenient charging and is secured by a key, while the listed 48V 25A controller manages power delivery.

01 / CAPACITY

Approximately 1200Wh

Capacity is calculated from the published 48V and 25Ah figures. Actual usable energy may differ because of system protection, temperature, battery age and operating conditions.

02 / RANGE

Up to 80 published miles

Maximum-range testing conditions are not fully detailed. Higher speeds, frequent starts, hills, wind, low tire pressure, cold weather and heavier loads can substantially reduce distance.

03 / CHARGING

Approximately 5–6 hours

The listed charging input supports 100–240V AC. Use only the supplied compatible charger in a dry, ventilated location and follow the instructions in the included manual.

IP54-rated electrical system

IP54 indicates limited dust ingress protection and resistance to water splashes under defined test conditions. It does not mean waterproof: avoid submersion, deep water and high-pressure washing.

Comfort and practical control

The EK7 combines a step-through carbon-steel frame with an adjustable saddle, front suspension, full-size wheels and useful lighting for a natural everyday riding position.

Comfort

Suspension front fork

Front suspension helps absorb small impacts and vibration from cracked pavement and uneven surfaces.

Fit

Adjustable cushioned saddle

A soft saddle with shock-absorbing construction allows height adjustment for a more natural posture.

Tires

26 × 1.95-inch profile

Full-size spoke wheels support efficient rolling and predictable handling on ordinary urban surfaces.

Stopping

180mm mechanical discs

Front and rear disc brakes use motor-cutoff levers to interrupt drive response when braking.

Visibility

LED front and brake lights

A front lamp supports forward visibility while the integrated rear brake light alerts traffic behind.

Utility

Large rear cargo rack

The rear platform provides space for compatible bags or properly secured cargo within all load limits.

Important capacity clarification

The same reference page gives two different maximum-load figures: 400 lb in its detailed table and 330 lb in its feature summary. Until the exact unit label or manual confirms otherwise, use 330 lb as the conservative combined rider-and-cargo limit.

Before the first ride

Set up and inspect carefully

Final assembly and adjustment may be required after delivery. Follow the included manual exactly and use a qualified technician whenever you are uncertain about brakes, steering or electrical connections.

  1. Inspect the delivery. Check the carton and every component for damage or missing hardware.
  2. Complete assembly. Secure the front wheel, handlebar, pedals, saddle, lighting and accessories.
  3. Charge safely. Use the supplied charger on a dry, stable and nonflammable surface.
  4. Verify critical controls. Check tire pressure, wheel security, steering, brakes and motor cutoff.
  5. Confirm visibility equipment. Test the display, front lamp, rear brake light and reflectors.
  6. Begin at low assistance. Learn acceleration and stopping response in a clear area before regular use.

Frequently asked questions

Clear answers to the details customers usually want before choosing the EK7.

How fast can the EK7 travel?

The standard setting is listed at 20 mph and the published adjustable maximum is 28 mph. Actual speed depends on load, charge, terrain, conditions, setup and legally required local restrictions.

Can it really travel 80 miles?

Eighty miles is a published maximum, not a guaranteed result. Assistance level, throttle use, speed, hills, wind, temperature, tire pressure, load and battery condition all affect distance.

How long does charging take?

The detailed table lists approximately 5–6 hours for a full charge. Partial charging may take less time, while temperature and battery condition can change the result.

Can the battery be removed?

Yes. The 48V 25Ah lithium-ion battery is removable and key-secured, allowing charging either on or away from the main unit according to the manual.

What rider height does it accommodate?

The detailed specification lists 5′4″–6′4″. Another summary on the reference page extends the upper figure to 6′5″, so riders near either end should compare the published geometry with their preferred fit.

What is the maximum load?

The reference page conflicts: its detailed table states 400 lb while its feature summary states 330 lb. Use 330 lb as the conservative total rider-and-cargo limit until the exact supplied manual confirms otherwise.

Can it be used when the battery is empty?

It can still be propelled manually with the electrical system switched off, though its 65.3 lb listed operating weight means it will require more effort than a lightweight non-powered design.

Is it waterproof?

No. The listed IP54 rating indicates splash resistance under defined conditions, not protection from submersion or high-pressure water. Keep charging connections dry and follow the manual after wet use.

What warranty and return terms apply?

Coverage is determined by the policies offered by this store at the time of purchase. Review the Warranty Policy, Refund Policy and Shipping Policy before ordering.

Performance and safety notice

Published speed and range are potential figures under selected conditions and are not guaranteed for every rider or route. Weather, hills, surface, tire pressure, riding style, temperature, battery age and combined load can materially change performance.

Laws covering motor output, speed, throttle use, helmets, lighting, age, licensing, registration and permitted riding areas vary. The owner is responsible for confirming and following all local requirements.

Wear appropriate protective equipment, complete a pre-ride inspection and allow extra stopping distance on wet or loose surfaces. Never exceed the conservative 330 lb combined limit without written confirmation from the documentation supplied with the exact unit.
