Written Review

The Tern Vektron is a pretty amazing electric bike, folding or otherwise. I’ve been looking at images of it next to and overlapped with models from different companies and you can instantly see that the reach is longer and really the frame itself is longer. This improves stability, gives you more room to pedal without heal strikes on panniers and toe strikes on the front fender. Thanks to their Andros adjustable stem and telescoping seat post, you get full leg extension and a more comfortable or more aggressive body position depending on how you prefer to ride. I met with Steve Boyd for this review and got very detailed in the video. Definitely check out the pro’s and con’s below because there are lots of little extras to consider that might help to justify the higher price tag if you’re on a budget. This folding e-bike is sturdy, comes standard with all of the cargo and safety features you could want and offers one of the best warranties I’ve ever seen (5 years on the Tern parts standard or 10 years if you register). The Bosch drive system fits perfectly and blends in with the matte black frame. Weight is kept low and center and features like shift sensing let you use all ten gears smoothly without expert execution and timing. Stand out features to me are the pannier rails on the rack which have stoppers to keep bags from sliding off when you fold and roll the bike, a unique dual-clip bungee system, compatibility with Yepp and Maxi child seats, integrated LED lights with a capacitor to keep you illuminated for a minute after parking, forward compatibility with the larger Bosch Powerpack 500, quick release wheels, a magnet and rubber band stay-folded system and hydraulic disc brakes with adjustable reach levers. There is so much more on this bike to dig into, the video review is long but I had a blast learning from the GM of the United States and founding partner so do check it out ;)

Driving the bike is a 250 watt nominal mid-drive motor from Bosch. This is their Active Cruise model designed to feel smoother but it’s still very responsive. All current Bosch Centerdrives measure rear wheel speed, pedal cadence and pedal torque 1,000 times per second to deliver predictable power. The faster and harder you pedal, the more power you get… up to ~500 watts and 50 Newton meters peak. It’s a very capable system but I noticed that I didn’t zoom right up to 20 mph as quickly as with some of the full sized electric mountain bikes and city bikes I’ve tested. In order to hit top speed I arrowed up to Turbo mode using the display panel the switched to the higher gears. One thing I really love about the Bosch controller is that it delivers software driven shift sensing response so the chain, sprockets and derailleur aren’t damaged as easily. With higher end mountain bikes, I usually expect people to be thoughtful in how they shift but those motors offer up to 75 Nm of torque and the rider is often climbing and even standing up. For this folding bike, I found that mashing seemed almost non-existant and the drivetrain hardware, from Shimano, is well made and durable. In short, the motor keeps weight low and centered, is protected by two support bars (to keep it clean and scratch-free when the bike is folded) and it blends nicely with the all-black frame. You do hear it when pedaling at higher RPMs and in the more powerful assist levels but the soft electronic whine isn’t bad. I usually ride in the lower two levels of assist and get excellent range, 50+ miles per charge.

Powering the motor and both LED lights is a standard Bosch Powerpack 400. It’s compact, light weight at just 5.4 lbs and fits perfectly behind the seat tube. This is one of my favorite parts about how the drive system was fitted on the Vektron. Rather than force the battery onto the top tube or onto the rear rack which both cause problems (raising the stand over height or taking up space, weight capacity and destabilizing the bike) they extended the frame and pushed the rack back. I love that this battery can be taken off so easily, even without removing the seat post and saddle. It clicks on in a snap and has a solid locking core and metal latch which keep it from rattling while riding. The pack is surrounded on all sides by frame tubing so it will be safe if the bike tips or there’s an accident and it has an integrated loop handle at the top so you’ll be less likely to drop it while transporting off the bike, perhaps to charge it? The pack can be charged on the frame if you’d like and the charger is fast, offering 4 Amps of output vs. just 2 Amps on many other electric bike chargers. It’s compact, lightweight and connects in a way that feels solid like the pins won’t get bent. Note that Bosch now offers a 500 watt hour battery which is compatible with the Vektron and all other current designs. The pack is the same physical size but weighs more and costs more.

Operating the Tern Vektron is a snap, once the battery is charged and mounted correctly just press the power button along the top edge of the Purion display panel / button pad. This display is not removable like the larger Bosch Intuvia which makes me a little sad (especially for a folding bike which could get bumped around more) but it’s thin, easy to read and relatively easy to use considering it packs in almost all of the Intuvia features. You even get a 5 Volt Micro USB charging port on the left edge to use with a phone, music player or other portable electronic device. That amazed me to be honest, and I love that the walk mode worked with the demo bike we had because some of the older Bosch systems had it disabled for the USA. Walk-mode is great for times when you’re pushing the bike up a steep ramp or hanging out with a friend but carting around the bike with added bags and cargo. So once the display is on, you have to be in one of the four levels of assist to then press and hold walk along the lower edge of the control panel. I like that the Purion display lets you operate the lights by holding plus for a few seconds and that the headlight has its own on/off slider switch. The thing is very bright and I was told it’s a custom design from Herrmans. You can swivel it down or straight and it has some visibility along the sides with two small LEDs that stay lit for a while after the bike is shut down. This is a European feature that few e-bikes get in the USA. And that’s the thing about the Vektron, it only comes in one size and one color but it’s so adjustable and well designed that I think it will satisfy a wide range of use cases and they were able to keep the price down a bit through economies of scale. Sure, you probably feel like $3,400 is a lot of money but just a couple years back you couldn’t get any Bosch powered electric bike for under $4k, and that’s without a lot of the cool extras and premium components seen here.

Ultimately, the Vektron satisfies more than just the folding ebike scenario. It truly rides more like a full sized bicycle. The frame is longer, stiffer and more versatile but the weight isn’t unreasonable (at just under 50 lbs). Nice upgrades like locking Ergon GP1 grips, Shimano hydraulic disc brakes and a tight chain cover mean you really don’t need to accessorize the bike and they all look nice and just work well together. I appreciate when the manufacturer finds or designs parts that don’t rattle, stay out of the way and look good. The only area I’d think about upgrading is the seat post, perhaps adding a suspension seat post to improve comfort further. The larger tires help and in many places, if the roads are smooth this isn’t an issue. But if you truly plan to test the 40 to 80 mile range or take this thing traveling, the gel saddle and ergonomic grips might fall short and leave you with a stiff back and neck. Do adjust the bars and the seat post, take your time to remember what heights work best for you (using the markings on the post) then consider a 27.2 mm Thudbuster or Bodyfloat. I recommend going with a more premium post here because if you lift the bike by the nose of the saddle (as it is designed to do) one of the more basic suspension seat posts could break, they just aren’t as strong. Shout out to Tern, Josh and Steve for partnering with me for this review and hanging out at Interbike where I first got some insights to share back here.

Pros:

  • The frame feels solid but isn’t bulky, some folding ebikes have large joints that can bump your knees or theighs when mounting and pedaling but this one does not
  • I was really impressed by how quiet the Vektron rides, even at higher top speed, the rack system, lights and fenders stay quiet and feel sturdy
  • The front fender is extra long with an oversized build and mud flap, it should protect your feet and shins well and won’t get bent if you accidentally kick it while turning etc.
  • When folded, the bike really stays put thanks to a magnetic clasp AND rubber strap with multiple tightness holes… some folding e-bikes don’t have any systems to keep them from coming unfolded
  • The saddle is very cool, not only does it have a rounded plastic insert at the nose for you to use as a handle when moving the bike but it also has a pedal holster (for the quick-releasing right pedal when you fold the bike), note that carrying the bike by the seat when using a seat post suspension may cause damage to some cheaper suspension designs, consider 27.2 mm Thudbuster or Body Float
  • Beautiful aesthetic, it’s simple and clean with the black wires and cables blending in nicely along with the battery and motor casing
  • A lot of time and attention went into the buckle clasps, they lock securely, can be adjusted and even serviced with new bushings… and they don’t flop around (Tern has a patented flat-fold design)
  • I love the rear rack because it offers plenty of space on top and on the sides, it felt secure and can carry up to 55 lbs, the pannier bars on the sides have little metal protrusions to stop bags from sliding off the back when you fold and wheel the bike or if you’re noticing that your heel is striking your bags while pedaling (you can mount the bag further back to avoid this but know that the bag won’t slide off)
  • The Bosch charger is compact, relatively light weight and super fast putting out 4 Amps vs. most that just offer 2 Amps, you could toss it into a pannier, trunk bag or use the included bungee system to tie it down and bring it along (full charge in 3.5 hours)
  • This bike can be wheeled along with the bars when folded (as demonstrated in the video review above) and has a walk mode so it will help you carry its own weight, especially useful when coming up steep ramps from basements or carrying groceries etc. when unfolded and walking with a friend
  • High quality, full sized crank arms and pedals that don’t flex under force and weight, I like that instead of using cheap plastic folding pedals Tern developed a quick release system for the right pedal… the bike is still compact when folded but rides much better
  • Lots of safety elements going on here, you get protective lining in the tires, reflective stripes on the side, bright lights that run off the main battery and have windows on the sides so you can be seen from more directions
  • Premium hydraulic disc brakes front and rear, these things stop on a dime and are much easier to use and pull than mechanical disc or older style rim brakes, note that the brake levers can be adjusted to be closer or further from the grips depending on your hand size
  • Ergon locking grips feel nice and won’t twist under pressure or when you’re lifting and folding the bike or crack if the bike tips, just a nice upgrade
  • The Bosch Purion display is relatively easy to read, backlit, controls the lights and is easy to reach while gripping the left bar, you don’t have to take your hand off to use it (which improves safety) but it’s very intuitive to use still, each press of the buttons delivers a nice tactile click and it has a 5 Volt Micro USB port built in for charging a phone, GPS or other portable electronic device
  • Both folding latches have a two-step unlock system so you won’t accidentally come unfolded while riding
  • I like that the seat post has clear markings on it so you can remember and re-adjust each time you fold and unfold the bike to the appropriate height
  • I think the way that they mounted the battery is wonderful, it doesn’t raise stand over height, doesn’t hang way off the back or take up rack space and can still be easily removed WITHOUT taking off the seat
  • The motor is mounted really well, it doesn’t hang down much and is protected by two tubes with plastic caps that allow the bike to rest evenly when folded… it’s one of the most stable folded electric bikes I have tried, many other designs tip easily
  • A larger chainring paired with a 10 speed cassette make pedaling feel natural, they designed it to ride like a normal full sized bicycle even though it has smaller 20″ wheels, it climbs very well and can reach 20 mph but I had to change gears to reach the top speed
  • The rear wheel dropout is raised a bit to allow for strong mounting of the disc brake and more space for the rack and fender eyeletts, I believe it also lowers the center of gravity on the bike
  • I like that both wheels feature quick release because it makes the bike easier to work on or fix flats on the go… just bring a spare tube, mini pump or CO2 in one of your bags
  • If you register the bike your warranty goes from 5 years to 10 years for the Tern frame and select components (the motor and battery are 2 years)

Cons:

  • The Tern Vektron is definitely one of the more expensive folding electric bikes, it offers premium components, a first class drive system and an amazing warranty but that comes at a price
  • As with many folding ebikes, you only get one frame size here and it’s a bit longer than normal (the reach is longer), you can dial it in with the Andros stem and by sliding the saddle rails
  • While I love that the seat raises so high, it wasn’t clear how you’d be able to raise the handle bars to match without some special accessory, the Andros adjustable stem helps a lot but some other folding electric bikes have telescoping handle posts to address this
  • There’s just one color choice here, if you buy a couple of these for a his and her setup it might be tricky to tell which is which uless you add some accessories ;)
  • The stand over height isn’t super low, Tern purposefully uses a curved tubing design for strength and puts their folding joint back a bit but this means you’ll have to step higher to get on than some competing models
  • I love that they included bottle cage bosses but probably wouldn’t mount a cage and bottle here because it would be nearly horizontal and might leak, consider a folding lock, mini-pump or other compact accessory (or a tight bottle!)
  • It’s great that Tern went with wider tires for their official electric bike offering because in my experience, you tend to ride at a higher average speed and for longer distances and comfort can be an issues. Otherwise, there’s no suspension fork or seat post suspension… consider a Thudbuster or other 27.2 mm after market seat post
  • The Bosch Purion display panel isn’t removable like the Bosch Intuvia but it’s much more compact and still delivers all of the same readouts (hold + to activate the lights, hold – to cycle through menus)
  • Unlike a lot of other premium full sized e-bikes, the wires are not internally routed on the Tern Vektron (which makes folding and repairing easier) but they could get snagged easier and the front wires might interfere with the optional front rack and cargo if you remove the head badge on the head tube and install a “luggage truss” on the “luggage socket”

Awesome! Your last name almost looked like "Bosch" to me for a moment, perhaps the Bosch drive system on the new Vektron was meant to be ;) in any case, have a blast at the Expo, my fingers are crossed for good weather for you! Glad you enjoyed the review Ken.

I am curious as to if the Vektron will upgrade the battery pack to the 2017 500 watt hour unit like most of the other Bosch powered bikes?
Is a suspension front fork a current or future option?
Tern isn't offering the 500Wh battery option, but it could be possible on the dealer level. I don't believe that a suspension fork is an option, but keep in mind the wide balloon tires act as a suspension in a lot of ways.

I just rode the Vektron at the Long Beach Expo. Great bike! Sounds like you can upgrade to the 500 watt motor, if you want. However at $1000 that turns the bike into a $4400 purchase. For my money the 400 watt is fine.

Also rode the Elink and for the price that is a nice option-especially with the internally geared hub and the $2000 price tag. Will be purchasing one or the other this week .

EBike Expo
Starting next week, the 2017 Electric Bike Expo 8-city tour kicks off in Long Beach, CA and through the year, will make its way across the country, visiting additional cities like San Francisco, Salt Lake City, Chicago, Minneapolis, Portland, Miami, and Philadelphia. Here is where you can follow along - www.electricbikeassociation.org

The new website for the tour reflects that we have brought the expo series under the control of a US-based, non-profit association designed to continue building communications between the industry and the general public. It is also an important market research tool that builds data from the consumer up. On average, more than 50% of our attendees have never ridden an eBike prior to the expos.

We are also working in conjunction with the NBDA to bring electric bike dealer education to 4 of our events and with PeopleforBikes.org and the BPSA's eBike initiative being part of the midway at each stop, we hope to spread the discussion of growing state legislation and advocacy to get eBikes approved for use in more places.

The event's presenting sponsor is Bosch, the track sponsor is Trek and Tempo raffles off a brand new bike in each city with the proceeds going to a local non-profit group involved in cycling.

The Long Beach event brings more than 120 different national brand bikes for consumers to test ride on more than a 25,000 sqft test track in the Long Beach Convention Center parking lot.
Happened to be in LA this weekend for a teachers conference and snuck over to the Long Beach Expo on Friday. I was really impressed with the Riese and Muller Nevo with the Nuvinci hub. Also it was great to finally ride the anticipated Vektron. What an awesome bike. It has come down to the Vektron and the Tern Elink for me. I prefer the Vektron, but enjoy the price of the Elink as well as the internally geared hub. Although it is tough to beat a Bosch mid-drive. Especially when my last name is Boesch.

I saw a more thorough discussion of just this feature on the recent Tern Vektron video review. It looks like that folder makes it very easy to "walk" the bike when it is folded, and even allows you to use a "walk" feature on the control while the ebike is folded to turn on the motor at low speed when walking up a hill or when the bike is heavily loaded

Been meaning to respond to what you said about the Tinker having better lights than the Vektron-do you really think the Tinker has better lights? Tern really talks up their front light.

The rear light on the Tern is really special. I was speaking more about the headlight, where I've always been a big fan of the Supernova light spec'd on the Tinker. The Tern does have good lights on it though.

My favorite compact bike is the Tern Vektron. Most ebike manufacturers say their motor systems don't need maintenance but the Bosch system is the only system where that has really proven to be true in our experience. Most of the bikes in our shop are Bosch powered for this reason.

Regarding the internally geared hub, there are slight advantages to it, but it's not a major difference from a derailleur if cared for. Either way you'll probably want to get a tune-up about once a year if you use the bike frequently, but that can be handled by any competent bike shop. If your budget is $3500 for a folding/compact bike I would recommend the Tern Vektron. If you could stretch it a bit and you'd like some upgraded parts you should consider the Tinker. The Tinker has a suspension fork, better lights, higher performance motor, a larger battery different drivetrain options. Both bikes are great, but I want to be clear the value is in each of the bikes for the money as well.

I hope that helps.

Kenny it's really my pleasure. We're considering the Link with the Bafang, but I'm still undecided. The reliability and service after sales on Bafang systems leaves much to be desired. The Bosch system has minimal issues to start with and if there is something that comes up we can get people back rolling very soon quickly. This is very important to us as I know it's important to our customers.

The Tinker and the Vektron have quick release in the front. Regarding the Nuvinci, it's quickly gaining popularity for its simplicity and ability to work well with a belt drive.

I'm at the barber at the moment and I have the R&M Nevo out with the Nuvinci and it's been a really pleasant ride. It's very similar to the Tinker we have. Although I think having the 28mph speed with the derailleur would be a lot of fun too! That's the setup I have on my Load demo and I really like that.

Too bead about the Vektron being stolen. When are the Tinkers
coming over" to the states? I guess I need to figure out how much I am willing to spend. I like the Vektron, but woud like to see what the Nuvinci is like to ride. Also the Tinker has the gates belt drive and some suspension. I have found as I do my search that it is almost as difficult as buying a car-too many options. Curious if you will be selling the Tern elink with the internally geared hub with 7 speeds? I know it is not sophisticated as the Tinker or Vektron, but $2000 might be a nice starting point for my first ebike. It has some of the same features as the Vektron, but only goes 15 mph and some other lower end specs-there I go again, it is like buying a car.

Chris you have been great as far as communicating with me! I appreciate you answering all of my questions and I think I only have one last one. Does the Tinker and Vektron both have quick release on the front and rear wheels.

Thanks Again

I know a little bit about the Vektron from the Tern site, but am curious about the Tinker. What is the weight of the bike and what is the range that the battery will last (I realize some of it depends on my weight and what PAS level I have it on). The Tinker City even with the suspension seatpost is still under 4K. Have those 2017 models come in yet or not? I heard the Vektron is due in February.

Thanks,

Ken
I know others addressed most of your questions. The Tinker is about 50lbs. If you look at the US site there are actually just two versions coming over, the Nuvinci and the HS Touring. Both are a little above 4K. We have the Nuvinci model in the shop and it's getting a lot of attention. The Vektron will be next month sometime. We actually had a early demo but it was stolen from our store unfortunately.

Here is a link to Bosch's range calculator. Specify the Bosch drive system (I think the Vektron is the Active Line) and then you can play with the other variables to see how they impact your range (in KM). It should at least give you a baseline for some max and min estimates:

... what is the range that the battery will last (I realize some of it depends on my weight and what PAS level I have it on) ...
Here is a link to Bosch's range calculator. Specify the Bosch drive system (I think the Vektron is the Active Line) and then you can play with the other variables to see how they impact your range (in KM). It should at least give you a baseline for some max and min estimates:

I know a little bit about the Vektron from the Tern site, but am curious about the Tinker. What is the weight of the bike and what is the range that the battery will last (I realize some of it depends on my weight and what PAS level I have it on). The Tinker City even with the suspension seatpost is still under 4K. Have those 2017 models come in yet or not? I heard the Vektron is due in February.

Thanks,

Ken
Ken the Tinker weights quoted on the R&M site found with the frame geometry specs are;
City is 22.9kg
Touring HS is 21.9kg
Nuvinci is 23.8kg
Battery range is a contentious area
I read somewhere that if you are using the max power setting, the battery usage is approx 10Wh/km
If this is correct then a 500Wh battery would give a range of about 50km or 30 miles
As you have said there are so many variables so I would use this calculation as an estimate only
No doubt others with actual experience will chime in with their thoughts

My favorite compact bike is the Tern Vektron. Most ebike manufacturers say their motor systems don't need maintenance but the Bosch system is the only system where that has really proven to be true in our experience. Most of the bikes in our shop are Bosch powered for this reason.

Regarding the internally geared hub, there are slight advantages to it, but it's not a major difference from a derailleur if cared for. Either way you'll probably want to get a tune-up about once a year if you use the bike frequently, but that can be handled by any competent bike shop. If your budget is $3500 for a folding/compact bike I would recommend the Tern Vektron. If you could stretch it a bit and you'd like some upgraded parts you should consider the Tinker. The Tinker has a suspension fork, better lights, higher performance motor, a larger battery different drivetrain options. Both bikes are great, but I want to be clear the value is in each of the bikes for the money as well.

I hope that helps.

Great review and I'm really interested in this bicycle. The folded dimensions you list read like it would fit in my car trunk, when placed on it's side. But listening to your other reviews mentioning sensitive components, this has the display on one side and the derailleur on the other. Do you think it's concern in general or would the cargo rack adequately protect the latter?

Riese & Muller Tinker i think make job more effective with hub-gear
and without folding its quite compact e-assist bike

Correct, there is no throttle mode on any of the Bosch systems at this time. In my experience the Turbo level of assist is very zipp and responsive like a throttle, but you still have to pedal to get it working

Awesome bike! I just couldnt believe this bike would go for 40-80 miles based on them but then i saw the displayer estimating 57 miles.. so i dont know (36v x 11ah you know..) but if this bike is capable of that range i say its really worth the investment; this is definitely the best folding premium ebike and the price well I just wished it was 1k less. Great review! you explained it all.

You're welcome. Actually Bosch say that their estimates tend to be a bit conservative. And of course it'll vary slightly based on tire pressure, etc. But I've been riding the bike more or less non-stop for a few months now and their (and our) estimates are quite accurate.

Lobo GC

Joshua, thank you so much. I just checked mine and worst case scenario is 42 miles on Eco and 60+ mile on a paradise day. It looks legit since they take into account so many things and you are right this drive system is high end so it should be very efficient. Really nice feature from Bosch.

The Bosch drivetrain is one of the most efficient out there. You can calculate the average range for any Bosch equipped ebike using the Bosch Range Cockpit here: https://www.bosch-ebike.com/en/service/range-cockpit/

I see the sexy bike in the vid icon and get excited. I watch the vid until I hear "$3,400" at which point I instantly close the vid shaking my head and asking myself why I bother. Seems EBR should stand for expensive bike review which is really frustrating. I wish someone would make reviews of e-bikes with more down-to-Earth prices. I would totally subscribe to something like that.

I bought a couple super affordable ebikes last year on Amazon and reviewed them with video etc. I try to mix things up with styles and prices... different brands. You can see them all back at the site.

$3400 is a big investment. But it's also expensive to make a really good quality ebike and the difference in quality and warranty and service is important when you're investing in something like this. If you look at ebikes using the Bosch system, they're all substantial investments but you'll find that they are all very solid bikes.

It looks really good. Definitely the best folding e-bike right now. I think it's expensive though. My favourite, the GoCycle is cheaper and more impressive looking and with the awesome pit-stop wheels. But that bike isn't exactly a folding bike in the way this one is. This is the one for when you need to fold quickly and you're in a rush. And it probably rides closer to a regular bike and looks comfortable.

+ElectricBikeReview.com I haven't ridden an ebike myself yet but I can see from your reviews that the Bosch system is great. So it would be nice to mash that with a really ultra modern design with a fully enclosed drivetrain.

Good assessment Chris, I like the GoCycle as well. It felt different, the materials seemed more plastic and lightweight (not a bad thing) whereas the Tern felt more like a normal bike. I prefer the Bosch drive system above most so that is a win with the Vektron

Great review! I have the Tern Link D8 with a 250W Bionx kit on it. I love certain things about it, but there are things I wish was better. I have been looking into center drive motors because changing a tire with a Bionx is a real pain plus the weight is in the back.

This bike is perfect! I will probably get this once my battery doesn't hold a charge. Unfortunately, Bionx stopped making the 250 Watt system and getting a battery is harder to find and I'm not happy about that. That's another reason why I want to go with a company like Bosch. Coming from a company that makes car parts as well, I think they will make sure I won't run into a problem getting batteries for years to come.

Hey visualray! Yeah, this ebike is pretty dialed in... I really like some things about BionX, like the mini throttle and regen, but agree with your points. Sorry to hear about the battery discontinuation. Did you know that BionX is also owned by a car company in Canada called Magna O_o
