Written Review

The Flash V1, priced at $1,999, is the first offering from Flash Bike and comes with some pretty cool tech as well as a sleek, urban frame that is surprisingly sturdy despite it’s single-tube design. It feels like the V1 is a great choice for shorter rides in an urban environment, especially because of it’s integrated GPS tracking system that keeps an eye on the bike whenever it’s armed. The V1 has a 500-watt geared hub motor, a top pedal-assist speed of 28 mph and estimated max range of 50 miles. I personally like the look of the V1 – the front and rear frame-lights remind me of a Vanmoof and the control center on the down tube looks like something you’d see on a Stromer, which is cool since those rides can run $5k+. In fact, I think the biggest selling point of the V1 is the tech itself. The control center, which is located on the top portion of the down tube, displays current speed, battery level via a seven-bar battery indicator and pedal-assist level. There’s also an app that can be used to sync to the bike, which displays a few more bits of information like trip time and a tripometer. But more than that, the bike also has GPS and cellular, and when synced with the app can tell you exactly where the bike is at any given time and also alerts the owner if someone is tampering with or trying to steal the bike. When the V1 is armed (as opposed to “off”) the motion sensors and GPS are activated. If the bike is jostled, a mild alarm sounds, and if it’s jostled again or moved from it’s current location, the bike emits a much louder beeping noise and also alerts the owner via a push notification to their cell phone. Very cool. There is, however, a downside to this tech: it’s always drawing power from the battery. This means the battery is always being drained just a little bit, and after a week or so of not riding, the battery can lose as much as 50% of its charge. So if you go on vacation and come back, you may have to charge the V1 back up a bit before riding. It’s important to note the V1 will still lose charge over time even if it is left plugged in since the charger shuts off once the bike reaches 100% charge. In other words, it doesn’t trickle charge.

The V1 has some other really interesting tech that I haven’t seen on other electric bikes before. Most notably, it has integrated front and rear running lights, a powerful 450-lumen front headlight with three power modes, turn signals, an 85 decibel horn and even a brake light that activates whenever the brake levers are depressed. I love this feature as I feel it provides some serious layers of added safety. The running lights are on whenever the bike is on, but the main headlight can be toggled off to save battery. The main headlight is great as far as beam pattern goes – it has decent spill and throw – but because it’s integrated into the frame itself, it can’t be adjusted. I think this is fine as Flash did a good job of setting the beam angle, but for those that want to angle it up and down themselves to help with different types of terrain, that won’t be possible. The V1 also has motor inhibitors, which automatically cut power to the motor whenever the brakes are activated. This is a great feature to save unnecessary wear and tear on the motor and to keep you safe and in control. The brakes themselves are relatively powerful thanks to the 180 mm rotors, but the brake levers are a bit basic, requiring more hand strength and not being adjustable like hydraulic levers. It would be great if the V1 had hydraulic brakes, or at least the option to upgrade to them, but even with the mechanical brakes I believe the stopping power is more than ample, especially since the V1 only weighs 45.7 pounds. It’s always a challenge trying to balance expensive premium parts against a reasonable price point and I feel that Flash has done a great job here overall.

Technically, the V1 has a top speed of 28 mph with pedal assist, but with the 500-watt hub motor, I found it difficult to reach that speed, even on flat terrain. Granted, I weigh 200 pounds and was carrying about 30 pounds of camera gear with me. Lighter riders may be able reach the top speed more easily. Having a throttle on an electric bike is great, but a potential issue with that can be accidental activation when at a standstill. However, with the V1, the pedal-assist mode always starts at 0 whenever the bike is turned on. So neither the pedal assist nor the throttle will activate until the rider manually increases the pedal assist mode to a positive setting. Just another cool safety feature with the V1. I was worried that with a top speed of 28 mph and a single-tube frame I would get some serious frame flex, but I didn’t find that to be the case at all. I think this can be attributed to the three gussets on the frame that add to the overall rigidity and structural integrity. The 12-magnet cadence sensor on the V1 is quite sensitive and activates with even the slightest pedaling. The motor also shuts off relatively quickly once I stop pedaling or pulled the brakes. Pedaling from 0 to almost 28 is efficient and the seven gears were just enough to cover it, but the drivetrain is another area that has been specced down to save money. The derailleur is an entry-level Shimano Tourney and the shifter is a big thumb design that stays out of the way of your button pad and throttle but isn’t as quick or easy to reach. Note that because there are button pads on both the left and right side along with brake levers that have motor inhibitors and the shifter piece, the cockpit is a bit crowded… so this even though the display panel is way down on the top tube, at least that isn’t adding more clutter up top.

So what’s the overall paradigm or philosophy of use for the V1? I initially thought it would be a good commuter bike, but there are a few aspects of this bike that, after some consideration, make me think it would be better suited for shorter jaunts through the city. First and foremost, while the battery is technically removable, it’s not at all easy to do so. In order to take out the battery, the rear wheel must first be taken off, then the cap on the end of the frame must be removed and finally the battery itself – probably not something you’d want to do while standing at a bike rack outside your favorite coffee shop. Because the battery isn’t super easy to remove, it means that (generally speaking) the bike must be taken inside to charge. For some, this may not be an issue, but I suspect not every office space and coffee shop would allow a bike inside. So because of this one feature, I really think the V1 is better suited for shorter treks as opposed to commuting long distances. The V1 also lacks suspension, which can make longer rides a little uncomfortable, and while you can opt for fenders from Flash, they don’t come stock. And as I’m sure you know, no fenders can equate to wet and dirty pants. There doesn’t appear to be any fender bosses, although there are some threaded eyelets on the back of the frame that look like they can be used for a cafe lock (or maybe a rack if you really get creative, based on where they are positioned). Of course, one could always go for aftermarket fenders that attach to the seat post but those rarely look as good as factory fenders, and they can be difficult to keep straight. All this to say, while the V1 could certainly be used for commuting in certain circumstances, it probably would be better for shorter trips.

The V1 has some seriously cool tech that can usually only be found on much more expensive bikes like the Stromers, but with a price tag of $1,999, it makes sense that Flash would have to save money somewhere. And it looks like they did this by going with mechanical disc brakes as opposed to hydraulic, an entry-level Tourney derailleur, non-adjustable brake levers and plastic pedals. Sure, you can replace those pedals for $25 with some Wellgo alloy platforms off of Amazon (and I would totally do this as I have larger feet) but even still, I think the V1 is a good bike for the money – it looks great and rides just as well, it has some really cool safety features like the turn signals, brake lights, headlight, horn and GPS and cellular and even even has a throttle, something I always like to use to get going after lights and stop signs. Big thanks to Flash for partnering with me on this review and to Nick for heading all the way out to California to talk about the V1 with me.


  • The V1 has an integrated control center in the down tube that displays current speed, battery level and pedal-assist level, and when paired with a smartphone via the Flash app, can notify the owner whenever the V1 is being tampered with as well as provide an exact location thanks to the integrated GPS and cellular (which is free!)
  • Integrated front and rear lights look clean and function well, with flashing running lights whenever the bike is on, three-mode front headlight, brake-activated back light and turn signals
  • Motor inhibitor automatically cuts power to the motor whenever the brakes are activated, preventing extra wear and tear on the motor itself by accidentally fighting against it while braking
  • The V1 offers both pedal-assist and throttle override, which means riders can pedal it like a traditional electric bike or just use the throttle if they want to treat it more like a scooter or moped (but the maximum speed of 28 mph is only achievable with the throttle)
  • Three gussets on the single-tube frame add tons of rigidity to prevent frame flex and speed wobble even when traveling at high rates of speed
  • large 180 mm mechanical disc brakes do a good job at providing ample stopping power, the cables can stretch and the brake levers require a bit more hand strength than hydraulic but they help to keep the cost down
  • The buttons on the left and right side of the handlebars make it easy to switch pedal-assist modes as well as toggle the front headlight on and off and use the horn
  • Smaller 26-inch tires add to the overall compact look and feel to the V1 and contribute to low standover height, which is great for people like me with shorter inseams
  • Price tag of $1,999 isn’t bad considering the tech that comes with the V1, there’s only one frame size but you do get three color choices


  • The integrated control center, while nice, is on the down tube, which can make actually viewing it while riding difficult and even dangerous, you have to really tilt your head down to see it and that obstructs the view in front of you
  • The battery isn’t easy to remove, limiting options for charging on the go, for those that want to treat this like a commuter bike they may find it difficult to bring the entire bike indoors to find an outlet… but it least it’s relatively lightweight at ~45 lbs whereas most competing products are 50+ lbs
  • It looks like the fork and rear portions of the bike have bosses for adding fenders or racks, but the pattern was unique so I’m not sure all aftermarket parts will work (the rear bosses were on top of the seat stays vs. the sides)
  • The front headlamp provides ample illumination for riding at night, but because it’s integrated into the frame itself, the beam angle can’t be adjusted up or down
  • While the gussets do stiffen up the bike and reduce frame flex, riders that weigh more than 200 pounds may experience some frame flex, this is just a side-effect of not having a more traditional triangle-frame bike that is renown for it’s structural integrity and rigidity
  • The GPS and cellular are awesome features, but they are constantly draining the battery and after a week or so of not riding the battery can lose as much as 50% of its charge, this can’t be avoided unless the bike is periodically unplugged and plugged back in to trickle charge it
  • The kick stand is located in the middle of the frame and interferes with the pedals when deployed, this can make pulling the bike backwards – like when it’s tightly stored in a garage – difficult
  • No suspension makes for a stiff ride and after long distances it can become uncomfortable, especially when riding at higher speeds! Consider swapping the stock post with a suspension seat post for more comfort (the ergonomic grips and saddle are nice)

Hi Dani! Nice to meet you, thanks for reaching out and great job on your website! I cannot read it or understand the language spoken in the videos but I can tell you’ve done a great job, very similar with weighing the scooter and showing the different parts. Yes, I’d love to remain in touch and possibly review the different products coming from your customers who are going into the USA. You can reach me directly using the contact page on EBR here.

Not picking on the Flash here, but there are just too many brands out there now, that are not paying attention to what ebike customers want, feel they NEED, and why they choose ebikes vs alternate moods of transport or physical recreation. The Flash’s fatal flaws are going to be: 1) no easy removal of battery, and 2) no throttle.

Anyone (at least in the midwest, and likely many other geographies for other reasons Im about to cite) is going to want an EASILY removable battery, for when the bike is not in use during winter months, AND many will want that for being able to carry a spare battery to gain distance or range for a trip on the ebike. The draining by the added features of GPS and motion detection, makes the need even greater. The benefit of those two, aren’t likely to off-set the downside of non-easy removal.

Most ebike riders also want a throttle here in the US. There are many uses for it, that include even safety reasons or purposes, such as (one example) in situations as being stopped on a hill, and wanting the quick ‘boost.’ This applies both to regular people, and ones who just aren’t up to physical fitness that they used to be, and want to get back biking again. (hence the purpose of ebikes for many in the first place). Just pedal assist doesn’t cut it for many buyers.

So what is happening here, is a dilution of the market for all ebike OEM entrants (i.e. meaning that each OEM doesn’t get enough volume to become sustainable, thus not helping the market to grow or buyers becoming disenchanted with their products and not advocating them enough to others), and fatal flaws taking an e-bike’s ranking from what could be a ‘9’ or ’10’ rating, on a scale of ‘1 to 10’, down to a 4 or 5. If the market has more than 50 brands out of 100 with these sorts of fatal flaws, it really slows the adoption of the ebikes into mainstream. It maybe hasn’t for Europe, but the market drivers for buying here in the US, are far different than there, with European people NEEDING/wanting them for transportation, and REALLY wanting them, as cars simply aren’t as viable there as they are here, and gas prices are 4 to 5 times what ours are here.

Its as if OEMs selling into the US keep hoping they can ‘shove’ these mid drives (which usually have no throttles) or throttle-less ebikes down the throats of the US consumers, and expect sales to really grow. I think they are over-estimating the fickle and highly particular US consumer. Its too bad, because a lot of these 100 or so brands could be much more than just ‘me-too’ offerings with some cool features, if they didn’t have the one or two fatal flaws.

Thanks for sharing your opinions and insights here Mike, I agree that there are some glaring opportunities for improvement, important features like off-bike charging and the draw of GPS etc. on this bike. Some of the brands are really starting to refine their offering and lower the price point, which is helping to drive adoption, reliability and the overall reputation. I’m excited to now see Bosch powered ebikes in the $2.5k range and many hub motor options (with throttle) in the $1.5k like Juiced Bikes, Rad Power Bikes, Populo, and E-Glide. Magnum is doing a great job in between the lowest price and higher price point while still making their bikes available through shops vs. online direct.

I agree about the battery issue, but the bike does have a throttle. I just used it last night. :-)

Hi guys! I receive emails and phone calls pretty regularly about ebikes and one user named John M. from Cave Creek Arizona sent the following message about his new RadMini. I appreciated the pictures and additional details that might be different from my https://electricbikereview.com/rad-power-bikes/radmini/ and wanted to share with all of you. I don't always have the time to do this and appreciate all of you posting on your own, but I do what I can, when I can :D

Hi Court, I have had my Rad Mini a week, put 140 miles on it, wanted to give you some initial feed back.

Box was a mess when it arrived, logged that with UPS. But inside all was good, no scratches, perfect. Took about an hour to unpack and build what little there was to do. Its a quality product, very complete, 2 instruction book, one half in Chinese, the other half in Chinglish!

Bike is comfortable, nice saddle, big fat tires and new front suspension. Handy carrier, now has small bike bag on the back for repair stuff, pump, tube, Slime etc. Longest I’ve run with hills, 32miles, 3 bars left. Even on hills I use 2-3-4 almost never throttle, sometimes for starting off from lights.

One major change, I added a 53T chainring with cranks, Mini is too low geared form me, now I can pedal up to about 18-19mph, over 20mph down hill, can only coast. That’s up from about 14-15mph. Did consider 56T chainring, but when folded, crank would have been supporting the weight of the bike, not the ‘U’ bracket. I’m looking for a stainless 6’ chain (144 links). Putting the 53T crank on, even with a longer 120 chain, can’t get into 1st on the rear cassette. No big deal, I’ll never use it. If you know of anyone that sells 7 speed stainless by the foot, please let me know.

Overall I’m thrilled with the product and its performance. Contacted Rad customer service a couple of times (about crank, not a problem) prompt courteous reply. Mini is better than expected, distance at least 35 maybe 40 miles the way I ride. Speed (did make a minor ‘adjustment’ in the control for 40kph) off road of course. On level ground throttle only it will get to 22mph ish.

Added an iPhone bracket (modified Otter box belt clip), mirror and throttle rocker since removed-using a wire tie now! And small flashing lights (white blob to left of controller).

Also, here’s an idea for getting the rear wheel off the ground for flats, chain maintenance etc. Use a piece of plastic pipe with a rubber foot on one end and slit on the other to clip into the chain guard. Pulls apart for easier storage!

My wife’s https://electricbikereview.com/ness/icon/ is arriving tomorrow, can’t wait to compare and contrast that with the Mini. My wife is 60lbs lighter than me, so thinking we’ll be equally matched when out together with the lighter bike. We are both avid ‘regular’ bikers (she triathlon, me mountain), we might be a bit fitter than some. There is a very active Face book group for Rad, got lots of tips there and of course your Rad forum.

Thanks for the brilliant reviews, keep them coming. Your expertise was the number one factor in making our eBike choices. If you ever get to the Scottsdale/Cave Creek AZ area, please look me up, need a bed or a beer. Or if you are in the San Juan, Victoria area etc, we live on a boat in the summer up there-that’s what the folding bikes are really for, exploring the islands once we dock.

Best wishes and thanks again. John.

I am looking for a tail light that has a mode where the light moves from left to right, similar to Cylon light or Knight Rider light. I know that some lights have a 'pulsating' or 'flashing' mode, and that is not what I am looking for. CatEye seems to have a TL-LD600 that does the job but I would like more choices for my hard-earned money. Any suggestions?

Why do you care about the lights being illegal when this whole thread is about making your bikes go above the legal speed? Yes pedaling you can go above 20, but like that throttle isn’t going to be used still.

I guess people for some reason automatically assume that we would lock it out. We have gone out of our way to make the platform as open as possible and still reach our performance targets. By design, the new controller's hardware is backwards compatible all CrossCurrents, RipCurrent and OceanCurrent. The software may have to flashed to match the bike.

I have a Vilano Neutron (36v 250w folding fat bike), and it uses a king meter km529. Currently, when I turn on the bike it flashes Error 24 which I have research indicates a "Hall Sensor" error either due to a loose wire or burnt out hall sensor. Before this error, I used it for a relatively long (~1hr constantly) uphill which was around 15% slope, so i think i might have pushed it abit too hard. I'm not sure whether that was what was the caused of this.

Anyway, i did open up the motor and i'm 99% sure I found what is wrong but just want to double check what I need to do (and where) to fix it. Please see these 2 photos:

As you can see, the circled GREEN wire is not connected at all. But I need to figure out where to solder it back to. Also I am wondering what the heck is all that "melted looking" black stuff? Is that intentional from the manufacturer to "hold" things down? I wonder what could have caused the green wire connection to come off.

Any advice would be appreciated. thanks!

Unfortunately my wife was hit by a car on her IGo electric Metro S. She is ok, other than some bruises, but the bike didn't fare as well. After replacing the front wheel, I notice now that there is a flashing wrench on the display. The Brake handle appears to be slightly bent, so is it possible that the motor cut off switch was damaged causing this flashing wrench, or is this indicative of some other issue?

Any help is much appreciated.

Greetings. I have the Neo cross, approx 2.5y old and 5700km done. So far no major issues other than running into a Error 13 here and then.
I normally just needed to clean the contact of the display and was fine for the next 1/2y.

Yesterday a bike shop replaced the coat of the back wheel. In addition I dropped the display after it was done and tried to power up the bike first time after repair and ran into the Error 13 few seconds after the battery icon was flashing (as normal).
I checked all connections (front and rear) and they seem to be ok.

What I can reproduce is that the display goes from error 13 back to normal for a few seconds when using either the left or right break before I see the error 13 again. However, the motor will not start at any time.

Beside dropping the display we also cleaned the display contacts again. The bike shop guy used a bit too much of the contact spray maybe (?). Can this cause issues like described here?

Other than that only the rear connection was unplugged to remove the wheel of cause. But again, contact look good.

Is there another connection below the battery I am not aware of?

Anyone seen the behavior that error 13 goes away temporarily after using the breaks? Normal or a indicator that I do not have a cable problem but something else?

Big up for your help. Bless.

Following a ride yesterday (which utilised 50% charge), I was putting gear away when I noticed my Bosch 500wh indicator lights were flashing. The first three bars would illuminate for about 2seconds, then go out for 8seconds, and repeat ad infinitum. Pressing the indicator button did nothing. Putting it on charge did nothing. I contacted the dealer who had never seen this before, but contacted Bosch while I was on the line. The advice was to hold the indicator button for about 10seconds to reset the battery. Unfortunately the button didn't have any effect. It was also suggested to check for cracks in the battery case as water may have found its way in, again nothing obvious. I had to go out for an hour, so left the battery on the garage floor well away from anything (just in case). When i returned the battery had returned to normal and could be charged, the button was operating as expected. I have since visited the dealer who has run a full diagnostic but no error codes have been recorded in any of the systems. The manual depicts certain error codes for battery being to cold, etc but not the flashing 3 bars I have experienced. Has anyone else experienced this phenomenon, or can shed light whether this was an error code?

@Blueflash Thanks! I'll definitely post a ride report. It's been cold and snowy here in Utah and I probably won't be riding it anytime soon. I did a 1x conversion on my Cannondale and use a 30t chainring. It's been pretty good with just leg power. I opted for 32t on the Bulls since it's got a motor and it's right in the middle of the two original rings.

The only QR Front Hub is the Grin one. It is adaptable to 9mm standard QR, 15 and 20 TA and is the lightest Direct Drive hub on the planet of its watt class. It also includes a built in torque arm that makes a very positive connection and in all my miles on the bike it has held the 9mm QR in place.

You are right about the 1mm axle size difference that all the other nutted axle hubs have which people mainly pull out the file for as you suggest. Taking 1/2mm off each side of the dropout is not that big a deal if it is done correctly. But there were incorrect procedures done that did result in failures that have obviously tainted the front hub system forever it seems. That said my V1 bike has a 9c motor with a nutted axle that I had the dropouts widened on. Oh, and they are carbon fiber. Using the proper washers and locking it all down with a torque arm has worked on that bike for a couple thousand miles also with no ill effect.

And the use of carbon is about weight but not flexibility. It is about its ability to dampen vibrations and have a softer ride quality than aluminum but are as or more stiff torsionally.

I did a group road ride a few weeks ago on my mid drive MTB just to see if I could hang and in the lowest mode and 15psi in the tires I was able to keep up just fine but they were only averaging about 20mph. I missed my hub bike though and the ability to vary my cadence without varying my speed.

I was really excited about the sale of the Stromer ST1 V1 bikes and picked the Elite version last Tuesday. Drove it out the store and not even 2 kilometers in to the ride the chain snapped off. Got it back to the store and they installed a new chain. Took it to work and back next day and I have to say riding this bike was the most uncomfortable ride I ever had. My lower back and my shoulders were killing me. Next day I took it to work (12km ride) and on my lunch break I wanted to go and pick up some food and some 50 meters in to the ride I get No_Comm error, showing battery empty (it was at 80%). Had to pedal the thing back to the store with no assist and leave it there overnight. They were really great about it and gave me a loaner to tie me over until they fix the issue. Next day I called in to check what the issue was and they told me that the motor needs to be replaced. At that point I returned the loaner and got a full refund. I was quite disappointed and was expecting something more reliable from Stromer.

I found the riding experience to be lacking. I am not sure why the bike has 4 assist levels because city/tour/power all felt the same. I could bring the bike to it's max speed on city with very little exertion and could not see any difference in other 2 modes. It came with 14Ah battery which is supposed to give you longer range but I found the rate of discharge after my daily commute does not support that claim. After doing my commute of some 24 km the battery would be almost down to 50% and I never changed in to higher assists than City.

what does max estimated range mean? Is that will low pedal assist medium assist or no assist? Also are these legal where speed is limited to 32 km per hour or 20 MPH?

What types of tires are on the bike? Looks like Kenda but I am not sure.

Looks like a great bike for urban center bike rental slots.

I really dig the minimalist look, the stop/turn signals, and I especially love the security system...but a non-removable battery, a computer display you have to look down to access, and the lack of a suspension fork pretty much kills this one for me.

in the future it'd be nice if you set your camera down and rode past it so we can see what the bike looks like being ridden. Would have been nice with this bike especially with the smaller tires and compact design. I reckon the reviewer probably looked like a cramped up doofus on that thing

that right handlebar is way too busy... most of those buttons should be on the left side so you can use your right hand to focus on running the throttle.

On second look at this vid, it's interesting how those simple headlight/taillight extensions really make the cool look. Without that tubular can-light design note, it would appear as an average low end ebike. There should be some name for that design - it's a top tube overhang

Hello Court-Missed ya! Nice bike, but the non-removable battery is a deal killer. I would have liked to see if the bike can reach the 28 mph mark without too much effort or otherwise. Some ebikes have a 250 or 500 watt motor, but seem to cutout to 50% power at certain speeds. I do like the design and features in bike color white for my preference. Easier to be seen in traffic.

I was thinking the same thing. If you've got a 28 MPH speed pedelec, show it going 28 MPH.
