    Hack my Controller

    Hence, "I don't know for sure", @AHicks. There are also 13 years of other serviceability unknowns with this 2007 Slane Ajax/Dmhc, such as viable number of crank sensors, mileage remaining on 10,000mi hub motor, Li-ion battery life/charge cycles, possibly the absence of newer desirable tech like...

    Hack my Controller

    @MrCaspan if it helps, it looks like a KD26E LED Display, it was common on lots of bikes from that time, including Ancheer Ebikes. PDF Manual attached. There doesn't look like there's much adjustability. Veteran member @harryS might have some suggestions for upgrades.

    Hack my Controller

    @MrCaspan I'm just seeing you have the "2007" model on your hub motor, not the 2020, which also explains the artifact on your handlebars. 😉 Have a look at your "display" connector...if the DMHC controller software is unchanged, an LCD-SW900, or similar, might be a comparatively simple...

    Hack my Controller

    @MrCaspan, I'm not very familiar with the Slane Ajax 48v fat Tire bike, or DMHC controllers, but it looks like there are two things you can do...first, put that controller back together, then: Hardware: Count the teeth on the smallest, outermost, "top gear" on rear freewheel and I'll bet you a...

    10 Step-Thru Ebikes For Consideration

    @Ebiker33 This is a good list of lovely quality bikes. We went with a Lectric XP Step Thru...500W (800W+ peak) brushless geared rear hub, at the semi-disposable sticker of $899. EBR Review (Sister model): We are going to de-badge and lock it outside and just bring in the battery, which is...

    Qualisports Dolphin vs Lectric XP

    @trevorm Yes. On flat ground, or descent, a noticeable 21.4% improvement in mechanical leverage. No more over-cadence, or pretending you have a gear you don't have, you'll be able to pedal for real and have some purchase on the chain, which is more stable. Be mentally aware that the terrain...

    Qualisports Dolphin vs Lectric XP

    @kmccune, my commute is super flat where I am, so went with the 11-28t. Truth be told, the only time I'd ever shift out of the 11t was if my battery was down to one bar and I needed to conserve juice. On the Quali Dolphin, it has a huge seatpost battery (maybe too much battery) and I've only...

    Qualisports Dolphin vs Lectric XP

    @kmccune, my Shimano came off pretty easily, and I retained it in case of any QC problem with the DNP...there were some reviews a few years ago about catastrophic failures etc. Knock on wood, so far so good with mine...1yr and counting. I have another one for install on the Lectric as soon as...

    Rad, Lectric or Qualisports

    @JMoto this sounds like a very lucky kid.

    Qualisports Dolphin vs Lectric XP

    Thank you @kmccune for mentioning the freewheel swap-out, that part is a good idea for stability and maintaining higher traffic mingling speeds @trevorm. The Shimano 14-28t freewheel set that comes with QS, Lectric, and a lot of ebikes can be swapped-out for an 11-28t freewheel. Deleting those...

    Can I put a frame lock on the front wheel (fork) instead?

    @Happymere there is no fool-proof bike security, except for good household insurance plan. I supplement lock(s) with the Boomerang GPS alarm (just took delivery of two), and/or the cheap Amazon motion activated 113dB hell-raisers that zip tie under the seat for around $15. Just need to journal...

    Qualisports Dolphin vs Lectric XP

    @trevorm, the Qualisports line use the newer Kunteng software and controllers. There should be a good range of newer displays you could swap in place of the OEM KT-LCD5, so long as they have the correct harness. For example, I use a full-color late 2019 KT-LCD8H w USB power port, and it has...

    Volador owners, can you answer my questions?

    @nj1266 in a word, YES. I've tinkered with larger crank rings as well. I've bought some that were way too big. The limit to the number of teeth on the main crank is a function of type of crankset, budget, rear chain stay clearance, chain links, and pedaling style (bigger ring = less ground...

    Qualisports Dolphin vs Lectric XP

    @trevorm, you can effectively set an unlimited "max trip speed" by raising it from 25kph to something ridiculous, like 70kph. I vaguely recall the default P1 setting from Kunteng was only about 87% of the potential full throttle. So I set that to 100, which used to be the QS default. I also like...

    Can I put a frame lock on the front wheel (fork) instead?

    Among other things, I have an ABUS Plus 5750L NR mounted on front fork with fork adapter kit, and the ABUS 1m plug-in chain, and it can be a good portable medium-risk security solution IMO when there's no rear frame geometry that makes better sense. I have a folder, so can halve the frame, plug...

    Qualisports Dolphin vs Lectric XP

    Decal-stripping will be the first order of business when our Lectric is unboxed. As a lifelong collector of tools I'll probably never need, few bring more immediate, and recurring gratification than the 3M Stripe Off Wheel w Mandrel. Brrrrrrrrrrrrrrrrrrrrp.

    Qualisports Dolphin vs Lectric XP

    @Mateo's Dad We have a Qualisports Dolphin and a Lectric XP Step Thru with shipping in final transport segment (after similar long wait). For sure, there are weak spots and compromises with both. Top speed is often artificially governed by power-assist controller settings - to reduce...

    Where to buy rear Dolphin rack.

    @Tinker the lefthand support leg on the Dolphin rear rack is not symmetrical with righthand, as it must curve clear of the rear brake caliper. I don't know if there are any aftermarket rear racks that articulate in the manner necessary and still price under the USD$69 OEM rack. Please post...

    Volador owners, can you answer my questions?

    @nj1266 I don't have a Volador and can't speak to that specific model, but the sister-model, Dolphin, with thicker heavier tires is about 15-16" wide when folded-up. The front basket sticks out a bit further, if you're riding with one. My Dolphin is 50lbs with front rack, frame lock...

    Elbicycles Sweden

    Just curious if anyone has bought an Elbi EL500 by Elbicycles Sweden and could relay their thoughts? It looks like an intriguing light front cargo design with a competitive price point. There is even a weird ET/Henry Thomas signature version for that special someone.
