Thin 7 upgrade recommendations and experiences

Recommended Posts

I am looking to do some upgrades to a sondors thin 7 I bought in December 2017.  Specifically, I am looking to get a controller and LCD. If I understand things correctly, I need to upgrade my controller (which right now is the stock 15 amp) to an aftermarket controller in order to use one of the newer LCD units.

What factors should I consider when deciding between a 20 amp controller vs. the 25 amp controller?  I recall reading that while a 25 amp controller will give more power, it may also reduce the battery range. Is that accurate?

If I get one of the controllers offered on sites such as  https://boltonebikes.com/collections/motor-controllers-and-displays/products/36v-48v-25a-sondors-motor-controller-free-shipping   will it be 'plug and play' on my Thin 7?   Will it mount in the same place as the stock controller? I seem to recall reading on another after market site (luna cycle, I believe) saying that some of their controller offerings might have to be mounted outside of the battery box and also splicing some wires/changing connections.

Will I be able to use my stock throttle? I have a thumb throttle, no power button on it.  

If I get that 25amp controller from boltonebikes, what are my options for LCD?  The color KT-LCD8H (which bolt on ebikes is sold out of right now) ?  The KD51C ?   or the older KT-LCD3 ? Just want to make sure everything I get works well together.

Thanks.

Battery capacity and range is determinate on many factors but if you intend to use your stock battery, look at it this way. You just stopped at 7-11 and bought a small coke. You’re very thirsty but trying to decide what straw to use. If you use the smallest stock 15amp straw, your coke will last you all the way back home while riding your Thin. The larger 20 amp straw will deliver more coke on every SUCK but and it will quench your thirst faster but you’ll be out of Coke before you reach your neighborhood and still thirsty.   But you get the very large 25amp straw and suck a slug from your drink ..... now you’ve not only quenched your thirst but spilled coke all over your shirt from the acceleration and you haven’t even made it out of the parking lot of the 7-11. Okay, OKAY slight exaggeration , but the only way to maintain the range you have with the 15 amp controller when using one that delivers more current, it to ride like you still have a 15 amp controller and a use as little of the extra power, torque and acceleration the larger controller affords. Like anybody would ever do that. 

You should only buy your controller and new LCD (your old one will not be compatable with any other controller except your original) in a pairs from ONE vendor. Always ask all your other questions to  Kyle at Bolton. He is best suited to guide you on your best choices  but don’t expect much improvements with your stock battery and unfortunately there are not many battery upgrade options for the Thin, that fit in the Battery Triangel Box. You’ll want to think Rear  Rack or Brick Pack Battery Pack in Panniers. 

Performance upgrades are usually a trifecta: Controller, New Compatable LCD (individual preference no different in actual operation....color is purdy) and Battery of higher voltage (adds speed) and AmpHr (adds distance) . 

Before any upgrade attempt it’s important to gain some basic knowledge about the function of various components and electricity as it applies to eBikes. I’d recoment you review the technical articles at Electricbike.com  https://www.electricbike.com/   So your not disappointed in your purchases and understand what you’ll be accomplishing.

Hi Reddy,

Thanks for the great explanation and tips.  Since I don't even have an LCD yet, I think that just upgrading to get that will be an improvement (as I have read from several users that having the LCD is a huge improvement over not having one).  But your points are well taken that I should have appropriate understanding that I have a ceiling on performance gain if I only do the controller and LCD without doing the battery.

I thought the Thin 7’s came with an LCD Screen.  Yes, it will give you 5 levels of assist. If you buy an aftermarket LCD it won’t have the correct communication protocol for your stock Sondors 15amp controller. You’ll have to buy the correct COMPATABLE LCD from Sondors., $149.99. But for about the same or less  moola, depending on which LCD you select, you can buy the 20 or 25amp generic controller and generic LCD from any number of Sondors friendly suppliers. Bolton is doing the best on service, communication and after purchase support. It will cost you about $120 bucks, I think. 

Your range concerns can be mitigated by buying a second Sondors battery and carry it in panniers and exchange to double your trip length for $299.

The Thin 7 I bought in December 2017 direct from Sondors did not come with an LCD - so just getting any LCD is going to be a nice upgrade for me.

I am looking at Bolton for the 25 amp controller ($60), but unfortunately they are sold out at the moment of the color KT-LCD8H (listed for $90).  And per your advice, I am looking to work with the same supplier for LCD/controller to ensure compatibility. 

And good tip on picking up a 2nd Sondors battery for range doubling!

I did not know that! !

Electrobikeworld has the same components but I don’t know how they compare on price. They are Long Time Sondors Supporters and Forum members.  Excellent Service and Support. Email or Talk to Nick about your plans.
