Hi Craig! Sorry for the delayed response here… extremely busy times including some family stuff going on right now. Given your mostly road + a bit of gravel and the desire to go fast and far I’d recommend the Focus Thron Impulse Speed… This thing goes up to 28 mph, has a range of 100+ depending on the assist level you use, offers slick but cushy tires for road but also has full suspension for a bit of trail. Given your height, this bike would offer an excellent fit because it comes in four frame sizes and you’ll get a lot of utility with the integrated lights and mirror for those longer rides which might expose you to different times of day and busy traffic. Your idea about adding an aftermarket bar is a good one and I’ve done just this on a hybrid Trek I used for commuting in Austin years ago. You could explore stems that are shorter and more angled (upwards) and bars that are swept back a bit so you don’t have to lean forward as much. The full suspension should really help with your back and neck and is very nice to have when riding at higher speeds for longer time periods. Honestly, 100 miles is a long way to go so I wouldn’t bother with an extra pack right away, feel your way into it because I’m sure it will be $700+. As for your wife, there are very few electric recumbents available. It seems that many people use a kit to convert their trike and BionX has been popular because it’s available in many wheel sizes, offers throttle and assist and has regeneration. As an alternative, you could explore the Ridekick Power Trailer but it’s much noisier than the gearless hubs from BionX. Either of these options allows you to choose the perfect bike first and then go electric. I hope this helps! The Stromer ST2, Specialized Turbo, Easy Motion Nitro City and IZIP E3 Dash are also good speed pedelecs but http://electricbikecharger.com get the same range or offer the same comfort as the Focus Thron.

Hi Danl, that sounds like a very high power motor. Most consumer ebikes are in the 36V-48V range, so if your motor is advertised as being rated for those higher voltages then it’s definitely a more serious motor. If you’re looking for a ready-built and relatively inexpensive battery, then something like this might work for you, though I haven’t personally used that battery. You can of course build your own battery just like I did in this article, and that way you’ll be sure to get exactly what you’re looking for. The AH’s required will depend on the quality of the battery. A batter rated for higher current will require fewer AH’s than a lower quality battery. I’d aim for at least 20AH, if not more on a motor of that size. It’s going to eat your battery quickly, so you’ll want more capacity to be able to ride longer.

For dd hubs, i think a big drawback is the cogging torque when pedalling unassisted. It may be unnoticable at 5-10mph, but trying cruising at a normal 15 mph and it has “flat” feeling. Freewheel in geared huib abd mid drives roll magnet -free and that should be mentioned, imo.

The Active Line drive is designed for casual, comfortable cruising and pairs particularly well with bikes equipped with an internally geared rear hub. Featuring the full suite of sensors – including cadence, speed, and torque, the Active Line offers great hill climbing torque for moderate to steep hills. The Active Line drive offers a maximum assist speed of 20 mph.

I am on his build list, in part due to the positive reviews here and on endless sphere. Hopefully I’ll have one in my hands in a while and will be able to truly evaluate whether it was worth the additional cost.

1C charging is too high for most Li-ion. It’s too much to ask for right now, to be able to charge an entire pack in one hour. It can be done, but it’s not healthy for the cells. Aim for 0.5C at the most. I usually don’t go past 0.3C on charging.

Also changing the fuse to a higher one could cause the wires to start a fire and the whole house would burn down if the wires are not thick enough. Also in sweden a fuse gets bigger as they are rated higher so you can fit a 20A fuse in a 10A slot, for safety.

I want to take the apart and use the cells to make a 48V 16.8ah battery. Would you advice against this? Would 48V provide a noticeable difference in the power of my motor? (It is a 500W Falco Direct Drive Hub Motor)

That’s exactly correct. You’d start by welding 10 parallel groups of 4 cells each, then you’d connect those 10 parallel groups in series to make one rectangular battery. I’ve done many 10s4p packs just like that for 36V 10ah ebike batteries.

Hi Craig, sounds like a fun setup! Honestly, power and efficiency are very difficult to calculate on ebikes because some motors list a nominal and peak while others do not. There is a potential leverage boost from a mid-drive like the Optibike has but it really depends on the system. The Pioneer series is much more basic than their R Series or something like the Bosch Centerdrive or Impulse 2.0 but that doesn’t mean those are more powerful, just more responsive. I do my best to provide an overview on here but I’m not able to actually compare “power” and usually don’t even get to find out the Amp rating on the systems. Knowing the motor wattage and battery voltage is a start… along with the motor type, but that only goes so far. I’m sorry, I guess trying it out is the best way to decide for yourself.

I’m sorry to hear about your bad experiences with AliExpress. I’ve done a lot of business there, and I’d say only around 5% of my transactions have been problematic. They have great buyer protection though and every time I’ve either gotten a full refund or had my product replaced at no cost. If you want a BMS from a source other than AliExpress or eBay, I recommend a company called BesTechPower. They make the highest quality BMS’s I’ve seen and they are the ones I use on my “top shelf” batteries. They are pricier, but you definitely get what you pay for. Just email their contact addresses and they can help you choose a BMS. http://www.bestechpower.com/

Thanks so much for the info, that sounds great and an exciting option! I understand the warranty issue but aside from that, you don’t see any issue than with building a battery of any capacity and just making the discharge cable with an xlr connection to plug into the bike. Would I need a different cable to charge the battery or does it charge via the xlr connection like theirs? Here is one more link with a few more answered questions about their auxiliary battery if you wanted more info. Thanks again, this is really exciting, I just want to make sure I don’t fry anything
