2) Try measuring the voltage of the battery while you plug it in and attempt to power the bike. If you see the voltage drop instantly when you turn on the bike, you’ll know you’ve likely got an issue with weak cells or a poor connection that causes a voltage sag issue.

Electric Bikes Are Now Legal on Pennsylvania Roadways! Breaking News… According to the Bicycle Access Council of PA in their November 2014 News and Digest, Electric-Assist bicycles are now legal on Pennsylvania roadways as part of Act 154. “Electric-Assist bicycles are now legal on Pennsylvania roadways as part of Act 154. In a convoluted way since first introduced in 2010, a last minute amendment was introduced by Representative Kevin Schreiber (D-95) with…

For this tutorial, I’ll be using the green Panasonic 18650PF cells shown above. Lately though I’ve been using 18650GA cells like these, which are a little bit more energy dense, meaning more battery in less space.

I built my own ebike using the Gearless hub motor conversion kit on line. it works great. now i want to convert one of those Fat Tire Beach Cruisers into an ebike, the problem is that they don’t have the pre-made motors already attached to the wheel. i would have to do this myself. is it possible? you just need to connect all of the spokes of the bike to the motor? what are your thoughts on the feasibility of this? great website. thanks, Bert

Hi Vincent! In my opinion, there are a whole bunch of great possibilities out there. Luna has high powered stuff and the BBSHD worked great for me when reviewing a Lectric Cycles conversion a year back (using their e-RAD kit). Of course I also like BionX but the stuff is more expensive and proprietary. I’m doing less conversions these days (at least review wise) so I’m a bit behind on the category. For me, the frame makes a big difference and depending on what sort of terrain I’m encountering I’ll lean towards hubs for smooth and zippy feel or mid-drive for better climbing with the understanding that it might wear my drivetrain down, especially without shift sensing. That’s one area where e-RAD and maybe Luna now too, have some good options and accessories.

My first question is whether a hybrid or a hard-tail mountain e-bike is best suited for my needs? Most hybrid models I have seen are set up for commuting and since I am a fair weather rider I have no need for added features such as fenders and lights. I do, however, desire the option to mount a rack. I love the versatility and looks of mountain bikes. Bull has a few HT mountain bike models (29ers and 27.5) that may work but wonder if the riding position may be too aggressive and/or the tires too wide (i.e., too inefficient) for riding on the paved road sections.

Yes, as I understand it, Nimh and NiCd batteries charge differently. I understand lithium batteries much better than those other technologies, so don’t quote me on this, but I believe that Nimh and NiCd cells have current powered through them and the voltage control is different, as opposed to lithium cells that draw current at the charger’s preset rate and then keep drawing until the voltage floats to 4.2V, at which point the already tapering charger’s current supply is cutoff and the battery is fully charged.

The most noteworthy battery supplier is based in the USA and is offering lithium packs based on high quality cells.  A new vendor in 2015 is Lunacycle.com , so…check them out for a multitude of different packs at a very reasonable price.

Why does this formula work? Think about it: heat shrink (unless stated otherwise) usually has a 2:1 shrink ratio, so if I need something with less than twice the circumference (or perimeter rather, since my pack isn’t really a circle) of my pack. Since large diameter heat shrink is quoted in half circumference (flat width) sizes, and I want heat shrink with a circumference of a bit more than the perimeter of my pack, then I know I need the half circumference size to be a bit more than half batteries electric scooter my pack’s perimeter, which is equal to the height plus the width of my pack.

Your battery pack size is based on voltage and amp-hours. The higher the voltage and the higher the amp hours of your battery, the more range your battery will give you. A 48V 10-Ah pack gives you 480 watt hour (48 X 10). This gives you an easy way to determine exactly how much battery you are buying. The wattage of a battery is the only accurate determinant to judge what range your finished ebike will have.

Hi, I am trying to decide between motors for client, a fanatical surf fisherman, who wants to use his fat bike for surf fishing. He mostly heads out for his day’s fishing when the tide is low and the sand damp and compacted. But his return journey is often when the tide is in and his ride will then be above the high water mark and the sand will be soft and deep. So, the choices are:

A trail-worthy speed pedelec with premium accessories like aluminum fenders, integrated Supernova lights, a removable color LCD display, and regenerative braking. Very well balanced, especially for a hub-motor electric bike, the air fork, hollow-spindle bottom bracket,……

The current GNG mid drive uses a 30% wider belt among several other improvements (stronger bracket, long lasting components, much better crankset). I don’t doubt the quality of the Lightning Rod unit, but I sure am not going to pay double for what to me are minor improvements (improvements that have virtually zero impact anymore).

GNG now has a different version of the mid drive where the belt reduction (prone to failure) has been replaced by a gear drive at the end of the motor. Has anyone tried it? You can’t argue with the price, but what’s the quality and longevity?

very steep hills. The only two drawbacks of a geared motor is a higher possibility of wear due to more moving parts, and a higher noise level than a direct drive motor. But we believe the benefits far outweigh the drawbacks and make the BH Neo bikes a highly compelling option.

I’m a little worried that your batteries aren’t what you think they are. If they really are AA sized, which is rare in the lithium battery world, then they are not 3,000 mAh. Next, 10 cells in series is going to give you 36V, which is twice what your 18V drill is rated for. 5 cells in series and 2 in parallel would be a better method. I usually recommend a BMS but you can skip it if you have another way of diligently monitoring your cell voltages and then charging using an RC style balance charger like an iMaxB6 charger through an JST-XH connector.

Hi David, I sure hope so! The last time I visited the Focus/Kalkhoff offices in Southern California they said that more models were on the way. I plan to go back and do more updates and videos at some point but am currently traveling in Texas (lots of rain and wind in Dallas right now!) keep an eye out and I’ll post the review once it is shot 🙂

The single best manufacturer is BesTechPower, but their BMS’s are really expensive and they have a minimum order quantity of 2. For ‘best bang for your buck’ BMS’s I’d recommend Greentime BMS’s. They are great for most ebike applications outside of serious hotrods and speed machines. I use them on most of my packs.

Dang, I just realized what I did wrong. I had been thinking as I connected the sense lines it was arbitrary which end of the battery was B1 and which B13, but obviously it isn’t. B1 has to be the negative end and B13 has to be the positive end. Since I already cut the sense lines to length, I’ll need to put my replacement BMS on the opposite end of the pack.

Interesting… that’s a beefy looking electric bike! I haven’t heard of Falcon or tested this bike (or anything quiet like it) but the specs are impressive. Note that it’s actually not classified as an ebike due to the large motor, it would need to be 750 watts with a top speed limited to 20 mph, and this could create a liability issue if you crash and damage property or injure someone. Given your desired range, it seems like the super large battery pack would be good, it will impact weight and handling to some extent but that’s the trade, an alternative would be a mid-drive ebike with pedal assist like the Volton 350. Note that the Falcon website doesn’t have an address, just this phone number (855)-661-7337 so it feels less trustworthy than a local dealer or large company that is more willing to expose who they are and potentially offer ongoing support. Hope these thoughts help 🙂

I realize this isn’t as prescriptive as it could be, I think there are many models that could work for you but the sizing and possibly style are really up to you. I’d love to hear how it works or possibly which ones you’re zooming in on and please, share your story in the forums to help others once you get an ebike and have time to ride it around. You can also call me using the contact page info to chat a bit if you’d like 🙂

The battery maximum power = volts x amps, so if this 36V battery can deliver 30A continuous, that means it can deliver a maximum of 1,080 watts, though I would run it conservatively at a lower power level than that in most applications.

Lithium chemistry is considerably more expensive than the “old school” lead acid chemistry. If you are buying a battery pack or a bike that already has a battery pack, be familiar with the chemistry that you’re buying. For example, its hard to find a good e-bike for under a thousand dollars with a decent-sized lithium pack. Lithium is pricey. Be realistic in your expectations when e-bike shopping on how much the electric bike will cost compared to what kind of range, performance, and life expectancy you will get out of a lithium battery pack.

But what if you didn’t have to compromise? What if you could build your own ebike battery to your exact specifications? What if you could build a battery the perfect size for your bike, with all of the features you want, and do it for cheaper than retail? It’s easier than you think, and I’ll show you how below.

Hi Court. Thanks for your prompt response. Based on your input and further consideration I have narrowed my selection down to three Bulls e-stream brose MTB models: Evo 3 29er, Evo 3 FS 27.5 plus, and Evo 45 FS. I selected Bulls for a variety of reasons but I have to admit I am a pushover for good looks. Bulls offers a wide range of models and there is a dealer in PA within a reasonable drive from my home in MD. Unfortunately, they do not stock any MTBs but may be getting one or two in soon I can test out. I am still on the fence with regards to a full suspension bike but I realize my back is not getting any younger and I may learn to appreciate the extra comfort on the paved and unpaved hilly roads I ride. One of the suspension seat posts you suggested would definitely help with the hardtail but these are heavy and fast riding bikes (especially the EVO 45 FS which you reviewed in February) so if comfort is of prime concern a full suspension probably is the way to go.

I started out looking at something from Pedego, then saw some things from Specialized…and I think I even saw something from Ford???…then today I came across the Indiegogo campaign for the Flux eBike. I’m a complete novice about eBikes and have no idea what I should even be looking for or trying to avoid.

    Regarding the cell question, its a mixture of both. Cheap ebikes use cheap cells. You can bet the Sonders ebike had the cheapest cells available. Name brand ebikes usually use Samsung cells, but sometimes LG and occasionally Panasonic cells can be found in name brand ebikes (the Panasonics are some of the most expensive and so they are rarer). That being said, I’ve seen some shadier internet sites selling high quality (and genuine) Samsung/Panasonic packs, and I’ve seen some nice ebikes with some no-name cells. You should always check with the vendor/manufacturer if you want to ensure you’re getting good cells. Unfortunately, it can be hard to verify the cells yourself though without voiding the warranty, as they are usually sealed under shrink wrap. A good vendor will be happy to confirm the cells for you ahead of time and may even be able to show you some pictures of opened packs to verify.
    You can use any connectors you like. I’m a big fan of Anderson PowerPole connectors for the discharge leads. I used this other connector that I had in my parts bin for the discharge wires. I’m not sure what that type of connector is called, but if someone wants to let me know in the comments section then that’d be great!
    Most of the price involved these days in building an e-bike or buying a ready to go e-bike is the size and chemistry  of the battery pack. For the consumer its important to understand  the difference between a 24V, 36V, and 48V pack. Also know what a 10-Ah pack is compared to a 5-Ah pack.
    The GNG catalog lists this kit as the “450W brushless“. The second mid-drive on our list, is also a kit that can be added to just about any bicycle frame that you like (maybe 90% of them?). See our article on this awesome drive, here.
