Design and choices

E-bikes can seem pretty troublesome, nevertheless Swytch has carried out hundreds to keep up points easy with minimal components. In all probability probably the most seen components are the Vitality Pack and its handlebar mount. In distinction to standard e-bikes, this battery mounts in a second and removes merely as shortly making security and charging a breeze. The Vitality Pack is obtainable inside the 15k range Air or the 30k range Max.

The motor hub is a stunning polished silver and by no means rather a lot larger than a typical hub that it attracts any pointless consideration. It’s appropriate with disc brakes out of the sphere and the bundle I reviewed obtained right here with a 700c rim with sidewall brake surfaces for the bike I was to place in it on. The rim is obtainable in each silver or black.

The PAS system helps the system know how fast you may be pedaling by measuring how briskly 12 equally spaced magnets transfer a static sensor relaying that info as a lot because the motor controller to vary the assistance diploma.

Lastly, the handlebar present provides tempo info and means that you can modify assist ranges on the fly with useful thumb buttons all in a small compact bundle deal that doesn’t scream e-bike.


Sooner than you’ll arrange the Swytch Electrical Bike Conversion Bundle, it is important order a bundle with the correct components to your express bicycle. There are literally solely two key variables; wheel measurement and power pack measurement.

For those who occur to don’t know the wheel measurement of your bicycle, yow will uncover it on the sidewall of the tire. Being from the UK, Swytch makes use of the ETRTO system which stands for European Tyre and Rim Technical Organisation. It’s a bunch that was primarily based to help make sure that pneumatic tires and rims remained appropriate. A translation between inch and ETRTO sizing and a tire occasion are confirmed proper right here.

As for the Vitality Pack, the selection to make will most likely be how rather a lot range you want to get between charges. Selections are the Air 15k (9.3 miles) or Max 30k (18.6 miles). The Max Pack is about 10mm thicker, 10mm wider and 400g heavier with a greater ticket. Keep in mind that your bike will nonetheless carry out as a non-powered bike in case you choose to not activate the system or happen to deplete the battery, so lighter may be increased in that regard.

Okay, let’s converse arrange. It’s much like Swytch’s 1st Gen mannequin. This can be as quick as 20-Half-hour or take for for much longer counting on how express you may be with cable routing and dialing points in. Listed beneath are the steps…

  1. Arrange the handlebar mount: This mounts on both sides of your stem, and in addition you’ll wish to make use of a pair of the included shims on each side to match the diameter of your handlebar to the diameter of the mount clamps.

    Arrange the chosen shims after which tighten the 4 bolts evenly until the mount is protected. Make sure to not over-tighten.
  2. Arrange the doorway wheel: Take away your entrance wheel, let the air out of the tube/tire, after which take away the tire out of your wheel. In case your bike has disc brakes, make sure that to remove the brake rotor out of your earlier wheel and switch that over. Arrange your tube/tire on the model new Swytch entrance wheel and inflate the tire. Arrange your freshly drained wheel onto your bicycle. Be a part of the cable as a lot because the black receiver cable coming from the handlebar mount by aligning the arrows and pushing them collectively. You may even see on this {photograph} that I wound the cable twice throughout the fork leg to care for among the many further measurement that’s wished to swimsuit various bike sizes. NOTE: I found that the cable ties included with the bundle have been large brittle, so that you just’ll want to present your particular person. The very last item on this step is to please, please make sure that to appropriately tighten the axle nuts and readjust your brakes for the model new rim ground or disc brake alignment. We want anyone heading out on the freeway to have a well-secured wheel and dealing brakes.
  3. Arrange the PAS system: Assemble the two semicircle components throughout the crank spindle on the left (non-drive) facet of your bike after which lure them into the crank arm fixture with the retention spring ring. Then use the cable ties to protected the segmented fixture spherical your crank arm. Subsequent, you’ll discover the place to place the sensor on each your seat tube or down tube so that the sensor is aligned with the magnets ring you merely put in. The sensor have to be shut so that it may sense each magnet transfer, and in addition you’ll want to assure that the magnet ring stays parallel all through its rotation. Peel and stick the sensor after which use cable ties to basically lock it down. Lastly, run the cable up the underside tube within the route of the handlebar. NOTE: It is attainable you will want to use some painter’s tape or velcro straps as a substitute of cable ties until each half is linked and dealing. Then you’ll circle once more and cable tie each half in place as quickly as.

  4. Arrange the Present: You’ll want to mount this near your grip as you’ll modify your assist ranges whereas biking. It’s typically mounted on the left facet as a result of the correct facet often has gear shifters that shouldn’t be interfered with, however it absolutely may probably be mounted on the very best facet if required. NOTE: The supplied gadget does not have the 2.5mm hex key that you just need for this. And be very cautious to not over-tighten the clamp bolt. I haven’t had factors with this unit offered by Swytch, nevertheless have broken two comparable making an attempt gadgets from Bafang and EggRider inside the ultimate couple of years the place there isn’t loads of supplies throughout the hinge pin.

    Run the cable alongside the underside of your handlebar (cable tie in place) and be a part of it to the corresponding inexperienced cable from the handlebar mount cable cluster by aligning the groove and snapping them collectively. They make a very satisfying pop sound.
  5. After connecting the greens, the yellow flat connector on the far correct (above) connects to the PAS cable growing from step 3. The remaining cable connections are for added gear which may be obtainable individually. The blues are for brake sensors that scale back power to the motor within the occasion that they detect you’ve utilized the brakes. The ultimate yellow is for connecting a thumb or twist throttle. Take a look at legal guidelines in your area as which can or might be not licensed.


A pair quick notes to watch up on the Swytch Electrical Bike Conversion Bundle arrange course of.

  • The bundle I acquired did not embrace any written instructions. I did uncover an web information of their assist half along with a full PDF information which may be very detailed.
  • The present installs with a hex wrench measurement that is not included inside the gadget bundle.
  • Use your particular person, good top quality cable ties. I’m an infinite fan of these low-profile Cobra ties any the place your limbs might brush a cable tie.
  • I’m express with preserving cables neatly tucked away, and my favorite issue to do is determine on bikes so the arrange (and maintenance) took me a couple of great hours. It might undoubtedly be carried out in beneath Half-hour for merely an arrange.

Okay, so effectivity notes. The battery is the vital factor half to an e-bike and as well as most likely probably the most ceaselessly stolen half out on the streets. Compared with the primary know-how Swytch, this battery and one of the best ways it attaches to the handlebar mount are MAJOR enhancements. The very best lever (confirmed below) opens the jaw of the mount to let the battery be merely inserted sooner than clamping it once more down.

This new Vitality Pack merely fits into practically any bag and even some jean pockets, nevertheless the burden will most likely keep you from doing that. Battery arrange and elimination is totally executed and the one drawback will most likely be remembering to grab it as you lock up your bike.

To begin out up the system, press and keep the button on the best of the present after which you’ll start driving. My unit was defaulted to Mode 0 (no assist), nevertheless a quick press on the up arrow of the present switch to 1 by way of 5 rising the amount of assist. The system remembers your setting from proper right here out even by way of battery elimination cycles.

For those who occur to get to a really steep hill that has you strolling (happens to all of us), there’s a welcome “stroll assist” mode that you just entry by holding the down arrow always on the present. It provides power to the doorway wheel and strikes the bike alongside for you as you stroll. Pretty useful since your bike does weigh a bit further with this bundle.

The stock setup of 5 assist modes (+ off) labored good. Keep in mind that it’s set to solely current assist as a lot because the tempo prohibit set to your nation or space. Inside the US that’s 32kph/20mph for a class 1 e-bike. In Europe, it’s 25kph/15.5mph. The one time you’ll really uncover the prohibit is in case you’re cranking alongside correct spherical that cutoff tempo. When you hit the prohibit, the bike can out of the blue actually really feel heavy akin to you’re doing all the work which is unquestionably the case. After finding out the information, it does seems like among the many stock settings might be adjusted, nevertheless I haven’t found a goal to mess with it.

The power assistance is large straightforward in another case and in addition you’ll find yourself smiling, like hundreds. The precise bike I put on this on is my son’s single tempo from State Bicycle. Proper right here’s a sooner than {photograph}.

I had constructed a model new wheel set for him a while once more with a rear SRAM 2-speed kickback hub. It’s a cool system that switches between 2 gears by backpedaling momentarily. Pairing this with a entrance wheel motor labored good as you’re able to swap to a greater gear sooner than a hill with out cluttering up your handlebars with further controls. Proper right here’s the after {photograph}.

The one precise drawback I ran into is that the battery does not sleep in case you depart it linked to the handlebar mount. The LEDs hold lit if the battery is mounted and over the course of (a very moist) week it drained by 3/4. This does not happen in case you are taking away it from the mount which is what you’ll need to do to value it anyway. That course of is as simple as connecting it to the included charger. The LEDs increment as a result of the associated fee diploma will improve. Anticipate value events of spherical 1 hour for the Air battery pack and 2ish for the Max.

What I like

  • Successfully thought by way of system that converts practically any bike
  • Superior battery system that’s light and deters theft and doesn’t eat up space within the major triangle
  • Small present with merely the data and the controls you need
  • Love that they included precise devices and a bag to keep up them in

What I’d change

  • The battery desires a sleep mode if left linked to the mount
  • Desires to include a 2.5 hex key for the present mount (or spec a 3mm head screw)
  • Need top quality cable ties that don’t break instantly
  • Sturdiness concern on the present hinge clamp

Remaining concepts

The Swytch system is definitely a reduction. It installs merely, even with out a whole lot of motorcycle info and all nevertheless ensures an infinite smile in your face. For those who occur to’ve already purchased a bike you need, that may be a low-cost choice to get an e-bike with top quality power components and doubtless the best battery configurations within the market all on the bike you already have. What’s to not like about that?

Worth: ~$500 (counting on battery choice)
