I wrote it in English, but inexplicably, it's appearing in Spanish. My apologies.

Good morning:

Since September 2023, I've been using a Trek Domane+ SLR7 with a TQ HPR50 motor. It's been a great experience, but the motor was too powerful for my needs.

I recently bought the Scoot Fastlane 10 with a TR HPR40 motor. I've ridden 600 km with it, and so far, it's been a complete success, as it's the motor that best suits my needs as a cyclist.

However, there's a problem that left me with a very bad experience yesterday: after finishing a 90 km ride with 1700 m of elevation gain and never exceeding 80 watts of assistance, the motor, upon reaching 22% battery remaining, entered "RESERVE MODE" or "ACTIVATION THRESHOLD". This meant that only the Di2 rear derailleur was working, leaving both the front derailleur and the electric motor assistance disabled.

I'm very familiar with TQ motors (I've been using them for 3 years) and it's completely unacceptable that they cut out with 22% battery remaining. If it were at 10%, it would be understandable, but with a 290mAh battery, they can't leave me without assistance when I've used 78% of it.

Therefore, I would appreciate it if you could tell me how, through the app or the dealership, using the service dongle, I can reduce this reserve mode activation from 22% to 10%. This way, I can ensure that my rides never reach that insufficient 10% threshold. 22% is outrageous, and with such a small battery, it's completely unsustainable and unacceptable on a bike at this price point.

This is the first action I believe I can take before advising my fellow cyclists against this motor.

I await your urgent reply. Sincerely, Email Address


Lo redacté en inglés, pero inexplicablemente, me aparece en español, mis disculpas.

Buenos días:

Desde septiembre de 2023, uso una Trek Domane+ SLR7 con un motor TQ HPR50. Ha sido una gran experiencia, pero el motor era demasiado potente para mis necesidades.

Recientemente compré la Scoot Fastlane 10 con motor TR HPR40. He recorrido 600 km con él y, hasta ahora, ha sido un éxito total, ya que es el motor que mejor se adapta a mis necesidades como ciclista.

Sin embargo, hay un problema que me dejó con una experiencia muy mala ayer: tras terminar un recorrido de 90 km con 1700 m de desnivel y sin superar nunca los 80 vatios de asistencia, el motor, al alcanzar el 22% de batería restante, entró en modo "MODO RESERVA" o "UMBRAL DE ACTIVACIÓN". Esto significaba que solo funcionaba el desviador trasero Di2, dejando desactivado tanto el desviador delantero como la asistencia del motor eléctrico.

Estoy muy familiarizado con los motores TQ (los llevo usando 3 años) y es totalmente inaceptable que se apaguen con un 22% de batería aún en el aire. Si estuviera al 10%, sería comprensible, pero con una batería de 290mAh no pueden dejarme sin ayuda cuando he usado el 78% de ella.

Por lo tanto, agradecería que me dijeras cómo, a través de la app o del concesionario, mediante el dongle de servicio, puedo reducir esta activación del modo reserva del 22% al 10%. De esta manera, puedo asegurarme de que mis salidas nunca lleguen a ese umbral insuficiente del 10%. El 22% es indignante, y con una batería tan pequeña, es completamente insostenible e inaceptable en una bicicleta de este coste.

Esta es la primera acción que creo que puedo tomar antes de aconsejar a mis compañeros ciclistas en contra de este motor.

Espero tu respuesta urgente. Atentamente, Correo electo

How often have you fully charged the battery already? Battery level estimates are imprecise before the battery has gone through some full cycles. The battery management system has estimated 22%, but actually the batter was already nearly empty, producing a drop in voltage and invoking reserve. This should improve with the next few cycles. If not, there might also be a problem with the battery itself.

Since I bought it a month ago, I've charged it to 100% seven times.

Have you discharged the battery to zero prior to this incident? That is where the BMS learns the full charge profile…. From full charge, discharge to zero, then full recharge a few times per year should keep the estimates in a reasonable range.
