The 9 Best Electric Bikes Under 1000 Reviews

A bike is a two-wheeled locomotive that may be electric, fuel-driven or even manually operated by hands or feet. Some bikes have three wheels that make them more stable as compared to the two-wheeled. The common bikes in the world are the fuel-driven ones. However, electric bikes have gained a lot of popularity in the recent past. The best electric bike under 1000 can run for long without developing issues.

The use of bikes dates back in 1885 when Daimler Gottlieb and Wilhelm Maybach made Daimler Reitwagen. It had an internal combustion engine that used petroleum for propulsion. It was the first of its kind. The invention stimulated the urge to make bikes that are more advanced. In 1894, Hildebrand Wolfmüller began mass production of the locomotives. It eased transportation as people could ride long-distances within a short time.

Modern bikes have different features that favor riding in different kinds of terrains. Some of them can move within mountainous areas while others can only allow you to ride them on flat or slightly inclined terrains. Bikes for sporting are powerful. They can move at higher speeds and allow users to make amazing studs due to their nature of construction. Let us now shift our main attention to electric bikes.

What are Electric Bikes?

Electric bikes are kinds of two or three-wheeled bikes that use an integrated electric motor for propulsion. Some people call them e-bikes. The bikes also have pedals so that you can cycles when you feel like. However, they do not run fast like fuel-propelled bikes.

Most of them can run at a speed of 25km/h-32km/h. advanced electric bikes can run at a speed more than 40km/h. Electric bike motors are there to help you when you are tired of cycling, or when climbing a mountain.

Normally, the bikes also have a rechargeable battery that provides power for According to a certain report on electric bikes in 2013, electric bikes have replaced ordinary bicycles to a greater degree. and more people prefer to use electric bikes as compared to the ordinary ones since that is easy to use and so do not make you tired.

How do Electric Bikes Work?

As I mentioned before, electric bikes use motors for propulsion. Electric motors are devices that can rotate under influence of magnetic field when an electrical current passes within. The size and the amount of current that passes in the motor define the power output of the magnet.

The rotating mirror attached to a special rod that links to the bike’s chain. When the motor rotates, it rotates the chain thus offering a motion to the bike. The motor receives power from a battery.

The speed of the motor depends on the amount of electricity passing within. Some motors have gears while others are direct drives. Geared motors enable you to control the rotation speed of the motor to regulate your speed. Direct drive motors just move with uniform speed as long as the motor is on.

Can I Modify an Ordinary Bike into an Electric Bike?

Yes. You can fix an electric motor on your bike and make it electric. You can do the fixing using a belt-drive, chain drive, and a hub motor. You have to fix the motor system in the wheel hub. You then fix the stater on the axle solidly. Lastly, fix the magnets on the rear wheel to rotate with the wheel.

What are the 9 Best Electric Bikes under 1000?

After detailed research on electric bikes, I have come up with the following nine electric bikes, which I believe, are the best in the market. Have a look at the detailed review of each one of them and decide on your own which bike suits you or your child.

ANCHEER 500W/250W Electric Bike Adult Electric Mountain Bike

The ANCHEER eclectic bike has 26″ wheel that proves very effective for medium-height people. over, the bike frame is extremely strong. It has carbon steel that makes the ANCHEER bike very light for riding without getting tired easily. To make matters interesting, the handlebar is of aluminum alloy.

The bike can move with a speed of 20Mph. that means it is faster than an ordinary bike. In addition, it has comes with Removable 12.5Ah/8AH Lithium-Ion Battery which is the source of power for the bike.

Again, use the professional 21-speed gears on different terrains. Such speed gears help you to climb steep mountains with ease since you do not use your energy to climb.

  • Strong carbon steel
  • Light in nature
  • It has 21-gear speed
  • Removable 12.5Ah/8AH battery
  • It is easy to use

Jasion EB7 Foldable Electric Bike


Comfortable And Space-Saving

My parents recently retired after decades of working 14 hour shifts at their donut shop every… single… day of the year. It was time for them to enjoy their lives and to further bond with the grandchildren they love. First, my brothers and I gave our dad the Metakoo Cybertrack 100 to help him go up the hills and bike longer distances, and next, we had been on the lookout for a comfortable bicycle just tall enough for our 5’1″ mom. You would not believe how difficult that search had been because there were several criteria I wanted for her:

EB7 Foldable eBike /Jasion

  • Decent motor to aid with steep inclines
  • 7 or 21 speeds/gears for tackling difficult, uphill climbs
  • Pedal Assist System (PAS)
  • Easy to get on/off for a woman in her 60s
  • Comfortable ride with shock suspension
  • Fat tires for more balance and control
  • Detachable, large battery for long rides and convenient charging

Several bikes I had tested were made for riders who were at least 5’3″ tall, had lousy battery life, or had small diameter wheels that would make rides less comfortable for an older woman. The Jasion EB7 Foldable Electric Bike checked every box I was looking for, EXCEPT: it was listed for 5’2″ riders. Would the extra inch be a problem for my 5’1″ mom? Only one way to find out by test-driving it.

Why An eBike?

Electric bicycles have enabled our family to travel longer distances and visit more places even though many riders still shun them. They feel that motor assistance is cheating and I agree! Biking is as much a sport as it is recreational: on one hand, there are those who want to challenge their physical abilities, and on the other, it is a more leisure way to explore and bond with family and friends. Two children have steered the competitive me towards the latter as seeing the joy on their faces has even trumped the thrill I used to seek on the mountain trails. Towing them in our Burley D’Lite 2-Seat Trailer (with 45-100 lbs extra) was no joke: cramping up during a trip made for a PAINFUL ride home! That was when I really started to appreciate electric bikes — the motorized assistance on the uphill climbs and during the final return miles with tired legs had been a welcome blessing!

Googo SY26 with Burley D’Lite (25 Mi)

Bike or Scooter?

Electric scooters are more nimble to move around with — and in some cases, more fun — but local laws may prevent them from going onto the same paths as electric bicycles. Most can also be carried around more easily due to their more compact size and lighter weight. Personally, I prefer bikes because they are safer to operate, can (usually) go onto the same places that mechanical bicycles can operate, are (generally) allowed to carry an additional passenger, and if the battery runs out or fails, you can still pedal around. A scooter would stop to function without a battery.

In A Nutshell

Jasion’s 20″ Foldable Electric Bike (EB7) immediately hit me with its quality build. Despite the shipping box that could use more heavier-duty cardboard, the content arrived undamaged with good foam padding at the right places. The bike’s 59 lbs made it one of the heavier electric bicycles I had tested, but there was a reason for that: larger battery and stronger motor.

Assembly was straight-forward, although the instruction manual gave me a bit of a scare as its steps detailed putting together the individual components of the headset, front fork, and front brakes. “Holy moly!” I thought to myself, giving flashbacks on when I had to frustratingly try to figure out how to put together the individual, small pieces of a mechanical mountain bike a year ago for the first time. Thankfully, the stem, fork, and brakes were already pre-assembled, and all I had to do was mount the handlebar, attach the front wheel and headlight to the fork, add the seat and pedals, and off we went. I was pleasantly surprised that the front disc brakes were not rubbing and required no adjustment, but I am certain that your experience probably would vary since nearly EVERY bike I had put together needed some tweaking.

Ride performance was clean, smooth, and comfortable thanks to its fat tires and front AND rear suspension to smooth out bumps and rocky terrain. Shock absorption level could be adjusted for the front fork for increased pedaling efficiency. Fat tires (with low tire pressure) perform better on snow and sand than road or mountain ones by not sinking as much. Furthermore, the motor’s 500W of (nominal) power was strong, holding a 43% advantage over both my Googo SY26 and dad’s Metakoo Cybertrack 100 mountain eBikes. That meant a very sudden, Rapid speed increase that could feel out of control at times, but my mom handled it like a champ after a few minutes of riding. Yes, despite her being 5’1″ tall and the manufacturer claiming a design for persons of at least 5’2″ height, she comfortably mounted and dismounted without a single complaint. I test-rode it myself and wow, it definitely accelerated much faster than my Googo, and so I was confident it could handle hills better than mine — and it did indeed!

Fat tires, when deflated to a low pressure, perform better on snow and sand than road or mountain ones because they do not sink as much.

The Jasion had a very clean, streamlined look with cables tucked away nicely. A diagonal frame just under the seat and on top of the down tube provided an extra handle to carry the bike around with, though as I had stated, its 59 lbs would not be something my elderly mom would be happy to carry around. It took a bit of a struggle to unlock the stem and down tube, and it also was not easy (for my mother) to fold the frame in half, but with a bit of adjustment, it became more effortless without affecting the integrity and safety mechanism. You could certainly leave the bike as it was shipped since that would make it safer to operate.

Shifting between the 7 gears was effortless with a thumb and finger control mechanism, and the fat tires gave a very satisfying sound while zipping around the neighborhood park and up a few climbs. Power Assist (PAS) was available in 5 levels by default, and speed topped at a FAST 24.1 mph (38.8 km/h) without a rider. Legally, electric bikes cannot go faster than 20 mph to fall under the United States Class 2 designation, and in California, only Class 2 can ride on Class 1 bike paths. What does that mean? This bicycle’s motor was too fast to legally operate in California, but thankfully, the speed did drop to 20 mph with either my mom or myself riding on it. Either way, be sure to check with your local and State laws before you push the Jasion to its top speed.

Electronic controls found on the left side of the handlebar were easy to use and managed the headlight, horn, PAS level, power, and color display. The screen was easily readable under direct sunlight and provided a nice set of information, including battery and Power Assist levels, speed (current, average, max) in mph or km/h, trip time and odometer, and more. Programming options were available on the screen to control various settings — See PROGRAMMING section for more details. A covered USB port underneath the LCD allowed a mobile device to be charged, such as a phone used for map navigation.

The large, 480Wh-capacity, Li-Ion battery (10Ah @ 48V) gave the Jasion a significant advantage over any of the bikes I had previously tested, including my Googo’s 360Wh. Longer runtimes with a more powerful motor, although also with more weight: 25-45 miles on fully-electric and 40-55 miles with pedal assist (the manufacturer did claim more conservative numbers of 20-25 and 25-40 miles, respectively.) My past experience found that it should theoretically be able to handle at least 130 miles with PAS only used for short uphill climbs. I prefer pedaling most of the time for exercise/health purposes and only invoke the motor just enough to get up a hill. This can be done by twisting the throttle found on the right side of the handlebar: the more you turn it, the more power is invoked on-demand. That leads me to some of the things I did not like about this bicycle.

Jasion EB7 Foldable eBike

Unlike the Metakoo Cybertrack 100, every bike I had tested could not activate the throttle while PAS was turned off or set to level 0, the Jasion included. This perhaps is a safety feature to prevent accidental acceleration when power assist was disabled, but I really enjoyed Metakoo’s implementation because it allowed me to pedal unassisted at all times and ONLY power on the motor when I turned the throttle. The Jasion (and all other bikes) required changing the PAS to level 1 before the throttle could temporarily be activated. One would then have to change PAS back to 0 for non-motorized operation. It is a very minor gripe that I got over very easily with my Googo, and it perhaps is best for the rider’s safety to NOT allow on-demand assist with PAS off.

Two keys were included and required to operate the bike’s battery. So, do NOT lose them! The “ignition” could very annoyingly be found below the down tube over which some cabling ran, and the bicycle could not power on without leaving the key inside. That made me a bit upset even though the lock also served to secure the battery. If the key needed to be left in the ignition, then moving it to the handlebar or another accessible location instead would have made for easy insertion/removal (like the Evercross H5 eScooter). Having it at the bottom required one to crouch to align the key with the insertion hole, and if the key was in the incorrect locking position, it could potentially fall off and leave you scrambling to find it. I attached a velcro to it and the cable to prevent that from happening. Most riders would likely just decide to leave the key in at all times.

The battery was housed within the down tube and removing it was inconvenient: first, turn the key to the unlock position, then fold the frame in half to allow the battery to slide out. On the flip side, this mechanism kept the battery safely protected within the tube and also helped to keep the bike compact.

Front wheel skewer unfortunately was not the quick-release type. This made it harder to steal the tire, but also less convenient to fix flats without bringing a wrench to undo the bolts. One should note that the manual mentioned safety locks were included, but our Jasion had not. Customer service said that a pair would be mailed out.

Motor, Number by Crank, Fat Tire

The serial number was etched onto the bottom front of the stem, but curiously, I also found a different number on the frame by the left crank. This may lead to confusion for law enforcement trying to match the registered serial number in the event of a recovery.

Jasion included a 109W AC brick to charge the battery with in about 4-5 hours. The battery could be left charging within the down tube or removed for energizing by your desk.

Update 2/13/2023: The Jasion now comes with the rear rack included. Consider adding a rear rack seat cushion.

Despite the shortcomings I had mentioned — particularly the frustration of needing to leave the key inside the ignition underneath the down tube — this electric bicycle made my mom very happy. It was a joy to spin for both her and me, and the build quality and riding comfort were top-notch. For me, personally, the 500W motor provided for a very smooth acceleration, but keep in mind that it could scare a beginner rider for the first time when that initial power kicks in. I felt solidly in control and the suspension worked well in conjunction with the fat tires to even out the effects caused by rocky or shaky terrains. If Jasion could figure out how to move the ignition to the handlebar, I would have been an even happier rider, but then again, my mom does not mind at all. Solid, foldable bicycle.

  • When motor assistance level is set to 0, motor does not turn on, and you will pedal fully manual

Serial number is etched into the lower, front part of the stem tube for registration with local police to aid with recovery. However, there is a different number also found on the frame by the left crank. This may lead to confusion for law enforcement to match the registered serial number.

  • Arrived nearly fully assembled
  • Should take 15-20 mins to finish build, but took me significantly longer due to taking photos and making modifications with third-party additions and parts
  • Attach handlebar, pedals, front wheel, seat post, headlight, and make small, tuning adjustments to the front brake as needed
  • Surprisingly, the front disc brake needed no adjustment (this rarely happened with any bike I had previously built)
  • Manual detailed steps that had you build the headset, front fork, and front brakes from scratch, but luckily that was not the case with my unit. They already came pre-assembled (as it should!)

  • May accidentally lose the key during a ride if switched to the wrong position
  • Key could get damaged if down tube hits a hard object. It could also get dirty from mud
  • Key may not be replaceable

Ignition, Frame Folding Mechanism

  • No on-demand pedal assist while PAS is off (set to level 0). Minor gripe but would have been a nice-to-have
  • Googo and Ancheer were the same way. Only Metakoo’s Cybertrack 100 had the option to temporarily kick on the motor by turning the handlebar throttle
  • Could not find where to purchase an extra battery, not even on manufacturer’s website at

Aircraft Transport

Most, if not all, airlines prohibit electronic scooters and bikes that do not meet specific criteria. United Airlines, for example, allows collapsible ones whose battery is both removable and below 300 Wh. Southwest Airlines is more restrictive at 160 Wh. This bike’s battery is 480 Wh. Lithium-ion batteries are known to be volatile, and the higher their capacity, the more risky they are. Check with the airlines, TSA, and FAA for more details.

Bike Assembly

Here are some installation tips for those assembling their first bicycle. First, look at the below diagram to identify the major bike parts, then watch the Jasion-made YouTube video found right after.

Bike Repair Stands

I use a repair stand to help with assembly and maintenance. SereneLife SLBKRS3 has a maximum load capacity of 66.7 lbs — enough to carry most electric bikes without falling over.

SereneLife Bike Repair Stand, Metakoo Cybertrack 100 mountain eBike

For easier maintenance or assembly, a bike repair stand can save a lot of time and back pain. Be sure to get one that can hold up your bicycle’s weight.

Bike Parts

Bicycle Parts /Al2 (CC by 3.0, Wikimedia CurID 2995998)


Some third-party parts were replaced or added while I assembled the bike. I will point out which ones were not included by Jasion.

If you already know how to assemble a bike, please skip to the next section.

Have included tools ready. Remove all protective material.

Securely clamp the handlebar. The handlebar should be secured to the stem with 4 bolts in alternating, opposite order. It is very important the bolts are securely tightened to prevent handles from coming loose while riding.

Mount front wheel to front fork, attach headlight, and pedals. Loosen the wheel’s two nuts, fasten wheel to the front fork (with disc brake on the same side as the rear one), attach the safety locks, and then re-tighten the bolts. The arrows on the disc brake should be pointing in the same direction as the ones found on the side of the tire. Attach the headlight to the front fork.

Front Wheel, Nut Cover, Headlight

Note the “L” and “R” label on each pedal and use a wrench to securely mount them in the appropriate direction to the crank arms. Left pedal tightens counterclockwise, right one secures clockwise.

You could replace the factory ones with Kootu Folding Pedals to help save space while in storage. Below is an example from my Googo SY26 review:

Attach pedals to crank arms

Check rear derailleur protector. You may have to pull the protector a bit until it hovers nicely over the derailleur. It should be cleared enough for the derailleur to freely switch gears. Our Jaison‘s drivetrain needed to have the chain placed back onto the front chainring. Do so by pushing the rear derailleur down and towards the front to give the chain some slack.

Place chain onto front chainring as needed

Install seat post, then inflate tires. Tires are sized 20 x 3.0 (20″), use Schrader valves, and should be inflated to no more than 35 psi. I added spoke reflectors for increased visibility. Esuik Dual-Cylinder Foot Pump was used to inflate the tires.

Attach the tail light as needed, adjust the seat post to the proper height (legs should be slightly bent at a 160 degree angle while seated and with foot on pedal at its lowest position), and do not lift the seat post beyond its maximum height line. Finally, fine tune disc brakes, brake handles, and gear shifters as needed.

Battery Tail Light (Warning: alternating Red/Blue lights may be illegal due to police association)


To enter programming mode: Press the “M” button twice until “P1” shows on the LCD. Cycle through the options with the “M” button, change values with “” or “-“, and save the changed setting(s) by leaving the screen for a few seconds or pressing “M”. Press “M” twice to exit programming.

  • 25:Brake Abnormality. Often a result of holding down the brake handle while turning the bike on
  • 30:Communication Failure. Often a result of a connection error between the display and controller. Check if all plugs are connected properly or have been damaged

Motor Bike Laws

I first learned about laws governing motorized scooters when reviewing the Joyor X5S, and unfortunately, they were (and still are) not straight-forward. There had been a number of accidents involving scooters hitting pedestrians or riders hurting themselves. I get it. Laws are there to protect people from each other and themselves, especially from irresponsible individuals.

Electric bikes can result in severe injuries or death with their high speeds.

Surprisingly, the laws governing electric BIKES are much more lax. They are very similar to non-motorized bikes, in fact! There are different classes of eBikes. This Jasion falls under the lower-speed Class 2 with a maximum of up to 20 mph, and as such, can be used on Class 1 bike paths in California. All 3 classes can ride on the protected, one-way Class 2 bike lanes found on streets and highways. Be sure to check with your local regulations. Some States categorize eBikes as mopeds or motor vehicles.

  • Class 1: PAS-only with no throttle. Max assisted speed: 20 mph
  • Class 2: PAS and throttle. Max assisted speed: 20 mph
  • Class 3: PAS-only with no throttle. Max assisted speed: 28 mph

California Law

Disclaimer: I AM NOT A LAWYER. Please consult your local city, police department, and/or legal professional for advice.

The following is my interpretation of how I understand the law. It has been shortened to only point out parts that I found interesting or noteworthy.

Mountain biking with Cybertrack 100 /Metakoo

  • Does NOT require riding with a Driver’s License or Instruction Permit (eScooters require them!)
  • No license plate required
  • Passengers are allowed as long as the bike was designed for it
  • Can ride on existing bike infrastructure
  • Speed limited to 20 mph
  • Follow most of the same laws as non-motorized bicycles
  • Helmet required for riders 17 years and younger
  • No minimum age limit

Final Thoughts

The search for an electric bike for my mom’s height of 5’1″ was a long one. It was incredibly difficult to find a foldable one for her height with at least 7 gear shifts and fat tires for better balance and control. Safety, ease of mount/dismount, and long battery life were also important as I did not want an elderly woman to get hurt or overexert on one of our long family rides. Jasion’s EB7 Foldable Electric Bicycle, despite my main frustration with the ignition’s location, has checked every criteria I sought for her. It is well-built, was smooth to ride on, and had quite the acceleration with its 500W of nominal power. I may look to replace the front wheel with a quick-release skewer to make it easier to fix a flat tire out on the field and also add a cargo rack.

Overall, the Jasion handled hills well (much better than my Googo or dad’s Metakoo, in fact), and the larger battery capacity should provide plenty of power to help mom not cramp up her thighs on the longer trips.

My family and I had very much enjoyed exploring town together instead of idling around in the car. It is both a healthy activity and a great way to bond with one another while building up the children’s confidence and endurance. I have not found myself going back to a non-motorized bicycle for daily rides, although I would still only take out my trusty Santa Cruz for more advanced mountain thrills.

Having the option to dynamically turn on or off electronic pedal assist is GREAT — that way, you can go manual, motor assisted, or all motorized.
